Gwyddion – Free SPM (AFM, SNOM #data #analysis #software #open #source



Gwyddion is a modular program for SPM (scanning probe microscopy) data visualization and analysis. Primarily it is intended for the analysis of height fields obtained by scanning probe microscopy techniques (AFM, MFM, STM, SNOM/NSOM) and it supports a lot of SPM data formats. However, it can be used for general height field and (greyscale) image processing, for instance for the analysis of profilometry data or thickness maps from imaging spectrophotometry.

Gwyddion provides a large number of data processing functions. including all the standardd statistical characterization, levelling and data correction, filtering or grain marking functions. And since the developers are active SPM users, the program also contains a number of specific, uncommon, odd and experimental data processing methods they found useful – and you may find them useful too.

Gwyddion is Free and Open Source software, covered by GNU General Public License. It aims to provide a modular program for 2D data processing and analysis that can be easily extended by third-party modules and scripts. Moreover, thanks to being free software, it provides the source code to developers and users, which makes easier both verification of its data processing algorithms and further program improvements.

Gwyddion works on GNU/Linux, Microsoft Windows, Mac OS X and FreeBSD operating systems on common architectures. All systems can be used also for developement. It has a modern graphical user interface based on the widely portable Gtk+ toolkit, consistent across all the supported systems.


2017-08-15: Version 2.49 “Window to the West” was released. As usual, it brings a bundle of new modules and various improvements – and also module bundles. The most noticeable changes are, nevertheless, a new much nicer icon set by Felix Kling and a better widget for adjusting the bazillion parameters of various algorithms. See the detailed news for the complete list of changes.

2017-08-12: Petr’s talk Gwyscan – library for smart scanning paths about gwyscan was added to presentations. See also the related paper .

2017-08-11: There seems to be still some interest in GIMP image generation plug-ins Yeti wrote 15 years ago – and abandoned essentially when Gwyddion development started. Although resurrection is unlikely, the good news is that their ideas have found their way into Gwyddion synthetic data modules. We added some information about the correspondence between them .

2017-05-11: A list of Gwyddion-related publications was added – more specifically, publications describing Gwyddion architecture and algorithms or otherwise related to the software in a fundamental manner.

2017-04-29: Version 2.48 “Magnetic Monastery” was released. It brings a bunch of MFM-related modules as well as the usual collection of new and improved file import modules and bugfixes. There is also a new translation, Brazilian Portugese. See the detailed news for the complete list of changes.

2017-01-18: A Fedora 25 repository was added. We are sorry for the delay.


2016-11-18: Version 2.47 “Pythocalypse” was released. It would be mostly a bugfix release, repairing selections that did not work properly in several modules. Except for one thing, a complete overhaul of pygwy (including a few API changes). And finally, Python scripting is also described in the user guide now. See the detailed news for the complete list of changes.

2016-10-31: A patch for version 2.46 was published, fixing broken function gwy_selection_set_data() that affects selections in Correct Affine, Measure Lattice, Straighten Path and a few other functions. See also Patches .

2016-10-18: A patch for version 2.46 was published, fixing compilation failure of the JPK scan file module when minizip is not available. See also Patches .

2016-10-14: Version 2.46 “Lichen Logistics” was released, bringing geometrical shape fitting, a new grain marking function, editable toolbox, new file modules and lots of other improvements. See the detailed news for the complete list of changes.

2016-09-04: Gwyddion has conquered space! The analysis of comet dust images from the Micro-Imaging Dust Analysis System (MIDAS) in the famous Rosetta space probe studying Comet 67P/Churyumov-Gerasimenko employed Gwyddion. See the ESA blog post and the full paper in Nature .

2016-07-21: A Fedora 24 repository was added. In related news, a patch for version 2.45 was published, fixing broken installation of API documentation with gtk-doc 1.25+ (which can in turn break package builds). See also Patches .

2016-07-20: A new version of the sample standalone module was released: threshold-example-2.5. A bug affecting the Mask mode was fixed and the handling of settings now more closely matches a typical Gwyddion module. A few pieces of the code were also slightly modernised (without increasing minimum required Gwyddion version).

2016-04-27: Version 1.2 of libgwyfile was released. The library was updated to handle new data types introduced in Gwyddion 2.45.

2016-04-26: Version 2.45 “Scatter and Slither” was released with a large number of new features, user interface improvements – and also initial native XYZ data support. See the detailed news for the complete list of changes.

2016-03-20: Some results, the ‘right’ values and remarks to the user influence survey are now available. See the description of each individual task for a link to the results and remarks. There may be some further elaboration and refinements, anyway, the results will hopefully satisfy your curiosity for now.

2016-03-01: The user influence survey is now closed. Thanks all who participated. We will publish the ‘right’ values and some remarks here after the Nanoscale conference.

2016-01-31: We have received a fair number of responses in the user influence survey so far and would like to thank all who participated. The survey form will be open to the end of February (which is also when the MS Windows installer will finally stop advertising it).

If you have not tested your data processing skills yet please download the survey images and fill your best estimates in the form. Thanks!

2016-01-12: Version 1.1 of libgwyfile was released, fixing a couple of bugs and improving error reporting and MSVC support.

2016-01-11: Version 2.44 “Entropy Everywhere” was released, bringing a few new features, but mainly lots of bug fixes and file format support improvements. As usual, the detailed news lists them all.


2015-12-20: A Fedora 23 repository was added. Note there were a few problems with various auxiliary developer scripts (cross build, night build, …) in F23. The scripts should be generally fixed in svn now.

2015-11-16: Complete MSVC development package is now available for Gwyddion compilation and development with Microsoft Visual Studio 2015. The package was prepared for Gwyddion 2.43 (the last stable version) and is still under development. Feedback is welcome.

2015-12-14: Please participate in our user influence survey in which we are trying to characterise the influence of humans on quantitative AFM results. The survey is fun because it consists of actual data processing (as opposed to just filling some boring forms) and it should not take more than several minutes of your time. At least unless you decide to figure out the absolutely best possible data processing procedures, in which case it can take an arbitrarily long time…

2015-12-10: If you use pygwy in MS Windows please avoid the Python 2.7.11 package (the latest one at this moment) because it causes a crash during Gwyddion startup. To stop the crashes once Python 2.7.11 has been already installed it is not sufficient to downgrade to a lower version. Apparently it is necessary to not only uninstall Python but also delete manually C:\Python27 and then reinstall all Python packages afresh. Known good versions:

  • 2.7.10 (or lower) for use in MS Windows
  • 2.7.9 (or lower) for cross-compilation in Linux

2015-11-25: Version 2.43 “Respectable Rotunda” was released. The number of improvements and bug fixes is large but they are scattered all over the program. See the detailed news for their full list.

2015-11-02: Broken Fedora 22 repository causing the RPM signature check to fail with ‘No such file or directory’ was hopefully fixed.

2015-10-07: Version 2.42 “Even Enlightenment” was released. The change everyone will probably notice is the new line correction module. There are however plenty of other improvements. See the detailed news for a full list of changes.

2015-07-29: We lost a few recent commits in the restoration of subversion repository from backup. The corresponding changes have been recommitted and subversion should be working normally now. However, the revision history since r17212 (including) has changed.

It is recommended to check out fresh working copies of all svn modules and transfer any changes you might have to the new copies. If you have a working copy updated to a r17212 or later, you must check it out afresh. If you observe anything odd with subversion please report it.

2015-07-16: There was a major outage of services due to a storage failure. File download works, but subversion, discussion, etc. are out of order at this moment. Details can be found at the SourceForge blog .

2015-07-13: Version 1.0 of libgwyfile was released. Several bugs were fixed since version 0.9 and MS Windows support was greatly improved. The library is considered stable now.

Dietary Supplements to Increase Fertility #fertility #source #companies


Dietary Supplements to Increase Fertility

by TRACY MORRIS Last Updated: Aug 13, 2015

Since 1997, Tracy Morris has written about fertility and medical topics for magazines such as “Achieving Families,” “ePregnancy,” “Nurses Lounge” and internet communities like MomsOnline. She has written for the clinics IntegraMed America, Shady Grove Fertility and RSC Bay Area. Morris has a Bachelor of Arts in human development/family studies from University of Houston and is a member of the Association of Health Care Journalists.

If you re trying to conceive and have a baby, you ve probably heard a lot about nutrition and fertility. Dietary supplements can serve as a secondary source of necessary nutrients for anyone, but the best way to make sure your body gets what it needs is through the foods you eat. If you re going to take supplements and you want to get pregnant, some nutrients are essential and others may or may not be helpful. Virtually no individual nutrient has been definitively linked to the benefit of boosting fertility levels, but there are a few that have researchers curious.


According to the American Dietetic Association, antioxidants can help prevent and repair cell damage, so they may have an impact on the quality of your egg or sperm cells. Vitamins C and E and selenium, a trace mineral, are examples of antioxidants which you can readily find in many foods. Supplementing with some nutrients, though, should be done with care. Fat-soluble vitamins, like vitamins A, D, E, and K, can build up in your system and cause serious medical conditions in you or your unborn baby, so you want to check with your health care practitioner or a registered dietitian about the safest amounts to take.


Coenzyme Q10, sometimes also called ubiquinone or CoQ10, is a fat-soluble antioxidant made by the human body. It helps your cells mitochondria make energy, and its levels are known to decrease as a person ages. Researchers from Italy concluded that oral CoQ10 supplements increased the amount of the substance in semen and improved sperm cell movement.


Women and men may benefit from adding more of the mineral zinc to their diet. In a mouse study published in 2010, zinc was found to be key to the egg cell s final development. And the American Dietetic Association says that zinc deficiency — along with not enough vitamin C — in men can cause sperm cells to move too poorly to result in conception.


The amino acid called L-Carnitine, or simply carnitine, is produce by your body with the purpose of helping turn fat into usable energy. The University of Maryland Medical Center says that sperm cells are one of the locations where your body stores carnitine and that low levels of the amino acid may negatively impact sperm count and mobility.

Necessary, But Not For Fertility

Folic acid, also called folate, is a B vitamin that can be deficient in even a typical American diet. Low levels of folate have been linked to birth defects like spina bifida, so you ll find the nutrient in any prenatal vitamin. Studies also lead experts to recommend that women begin taking 400 mcg of folic acid daily before they conceive and then throughout pregnancy for the optimally protective benefit.

Compound Supplements for Women

If you re a woman who s trying to conceive, you want to consider the health of your hoped-for embryo and fetus, as well as yourself. The safest and most reliable multi-vitamin and mineral supplement you can take is a prenatal vitamin. They contain nutrient levels that consistently test as both optimal and not harmful. Several products are on the market that combine nutritional supplements with herbs to promote fertility. The goal of these fertility-focused supplements is helping you achieve and maintain a hormonal balance that backs up the reproductive process.

Compound Supplements for Men

As with the women s version, the special fertility compounds for men also provide a simplified way of taking vitamins and herbs in one supplement. Rather than focusing on hormone balance, the male formulas aim at sperm health, combining vitamins, minerals, other nutrients and herbs that are believed to enhance the shape, movement, and even count of your sperm cells.


Research is ongoing to determine more connections between dietary supplements and fertility, but one thing that is known is you can take too much of a good thing. The American Dietetic Association, Shady Grove Fertility s Dr. Eric Levens, and the Mayo Clinic, among others, recommend you use caution when supplementing your diet. Be sure to read the label and any documented evidence of a product s safety and efficacy before trying it — especially if you re a woman trying to get pregnant, because not enough is known about potential risks to your unborn baby. Also, men and women who are going through fertility treatment should notify their health care specialists about any supplements in their diet. Even the makers of fertility compounds avoid recommending their products to female patients who are using certain types of medications.

    TerraER – Entity-Relationship Modeling Tool #terraer, #er #model, #database, #database #model,


    TerraER – Entity-Relationship Modeling Tool

    Henrique Rocha, Ricardo Terra

    TerraER is a free open-source learning tool designed to aid students in the creation of entity-relationship models. Our main goal is to provide students with a tool that reflects exactly the data modeling concepts learned in the classroom.

    Web Site:
    Version tested: TerraER 2.02
    System requirements: Java 1.5 or higher
    License Pricing: Open Source GNU Public License, Freeware.
    Support: Documentation available at our website and issue tracker system at

    Data modeling is one part of the database conceptual design process. The entity-relationship model (ER model) is a largely used conceptual model proposed by Chen [1]. It defines the entities and the relationships between these entities. The ER model is simple and easy to understand, making it intelligible to both database designers and end users [2, 3, 4].

    Academic database courses still adopt ER models to teach conceptual design. Nevertheless, we noticed a lack of modeling tools for this purpose. In practice, most modeling tools support logical design, which is a detailed model the designer proceeds after the conceptual model is complete. In view of such circumstances, academics (students and professors) are forced to use logical design tools instead, such as DBDesigner, ERWin, etc.

    The use of existing logical design tools – rather than conceptual design ones – has two major issues: (i) they may confuse students who are learning about conceptual modeling; and (ii) they were not developed for academic purposes. To address these shortcomings, we designed TerraER, a free open-source learning tool designed to aid students in the creation of ER models. Our main goal is to provide students with a tool that reflects exactly the data modeling concepts learned in the classroom.

    TerraER is distributed in a single JAR file publicly available for download at our web site The JAR file is auto-contained, i.e. it can be placed in any folder, does not require the installation of additional libraries, and does not change operating system files (e.g. windows registry). In a nutshell, TerraER requires only a Java Runtime Environment (JRE) previously installed on the target computer ( ).

    TerraER 2.02 has the following relevant features:

    • Free and open-source (GPL);
    • Simple and small but complete application (around 5 MB);
    • Cross-platform (only needs a JRE);
    • Internationalization (English and Portuguese);
    • Persist models to XML files (a cross-platform format);
    • Clipboard transfer;
    • Model printing; and
    • Easy to learn and intuitive interface.

    User Interface Feature description

    TerraER was initially designed for academic purposes, i.e. to help students and professors in the task of creating ER models. Therefore, we developed the graphical user interface to be practical, intelligible, and intuitive (i.e. easy to learn and use).

    The tool is a free, open-source application under the GNU Public License. Thereupon, we encourage users to directly contribute to the TerraER project ( ). As an example, a B.Sc. student has contributed to the project by developing the internationalization for the English language.

    Figure 1 � Screenshot of TerraER 2.02 modeling a hypothetical Banking ER

    The tool is developed in Java language, which makes TerraER a cross-platform application. In addition, new releases are always verified on Windows, Linux, and Mac OS.

    Figure 1 illustrates the TerraER interface, which is organized into five main parts:

    1. Menu bar. It provides the users with basic functionalities, such as saving, loading, and printing the models. More important, the models are saved in an XML-based format, which directly contributes to the cross-platform feature. In practice, models saved using an operating system can be loaded on a different one without any issue;
    2. Objects toolbar. It provides commands to create ER model elements – such as entities, relationships, attributes, etc. – on Chen �s notation, as adopted by Elmasri and Navathe [3];
    3. Position toolbar: It provides users with means to manipulate elements� position – such as alignment, overlapping, etc. – in order to support an elegant model design;
    4. Object inspector. It lists the elements of the current ER model and allows user to select, remove, or edit them. In practice, this feature provides a quick and precise way to handle model�s elements;
    5. Drawing area: It shows the graphical view of the ER model under creation. The user may add and remove elements to the model. There is a zoom feature, which can be very useful when dealing with large models. Also, there is a grid feature that displays a grid to help users to position elements.

    TerraER was initially designed as a teaching aid tool for academic database courses. In order to evaluate the applicability of our tool, we conducted a study in a Brazilian university to obtain the feedback from undergraduate students, which represent our target public.

    In the study, we defined three assignments and divided the database course class in 10 groups. In the first assignment, five groups were required to use DBDesigner (a popular database design system) and the other five groups to use TerraER. In the second assignment, we swapped the groups. In the third and last assignment, each group could opt for which tool they prefer. In the last day of the class, the students filled an evaluation form.

    The results clearly indicate a preference for TerraER as the model design tool. In fact, nine out of ten groups preferred TerraER to DBDesigner. According to the answers of the evaluation forms, the students argue that TerraER is easier to use and understand because it reflects the conceptual design learned inside the classroom.

    We welcome any help from the open-source community to support TerraER. For those not comfortable with their programming skills, it is possible to contribute with suggestions, donations, and even helping in the creation of a better documentation. TerraER source-code is available at , for those willing to play a more active roll.

    Academic courses still adopt ER model for database modeling. However, there is a severe lack of tools designed for this particularly purpose. In view of such circumstances, academics (professors and students) do not have other option than to rely on tools that do not follow the concepts learned inside the class. Even though these are usually popular tools, they do not draw conceptual models but logical models instead. In practice, it may negatively impact the learning curve of the students.

    To address this shortcoming, we developed TerraER with the specific purpose to be adopted in academic courses. Thereupon, we made the tool simple, easy to use, and complete w.r.t. ER modeling using Chen �s notation. More important, the study we conducted has shown students� preference for TerraER because it reflects the concepts learned in the classroom.

    Last but not least, TerraER is a small, multi-platform, free, and open-source software system, which make the tool the proper choice for conceptual data modeling. As far as we can guarantee, TerraER is currently (2013-year) employed in databases courses in ten Brazilian universities.

    13 Free Open Source NetFlow Analyzers (Windows #network #device #monitoring #open


    13 Free Open Source NetFlow Analyzers for Windows and Linux/Unix

    Looking for a Free Open Source NetFlow Analyzers for Windows, Linux or Unix? Look no further, we ve compiled the ultimate list of Open Source tools to help with your network monitoring tasks. As many of you already know, NetFlow is a protocol/standard developed by Cisco for collecting/transferring/analyzing network data using software packages to get a better understanding of what is happening on your network, along with further analysis of bandwidth usage, etc.

    Netflow allows administrators to take the processing of network data away from switches and routers and send the flow packets and information to a collector that further analyzes that data to free up resources on the network device itself.

    There are many commercial Netflow (or sflow, jflow, rflow, cflow, or netstream) that are Available for Free Download and use that we ve recently detailed in this post that are also Free of charge too. These Software packages are great if you are just getting into network analysis using Netflow, as they are designed to be Very user friendly and can be setup in relatively little time. Check them out HERE if you want to see what they re all about.

    On the other hand, if your looking for an Open-Source alternative, you re in luck We ve put together a large list of Free Open Source Netflow Analyzers/Collectors to help you collect, analyze and scrutinize traffic and bandwidth to help you keep track of whats going on in your network.

    Using a open source network analyzer/collector allows you the flexibility of customizing the software packages and reports as you wish if necessary. These software packages can be used on a wide variety of operating systems including Windows and Linux/Unix.

    Open Source Netflow Tools/Analyzers

    NTop (or Ntopng)

    Probably the most well-known open source traffic analyzers, Ntop, is a web-based tool that runs on Ubuntu x64 versions, CentOS/Redhat x64 Linux flavors, Windows x64 Operating systems, BeagleBoard ARM, Ubiquity networks EdgeRouter and even Mac OSX per their github site. nTopng also includes suuport for sFlow and IPFIX (through nProbe add-on), as its becoming a new standard that many manufacturers are using for flow analysis. RRD is used for databases and storing of data on a per-host level.

  • Flow-tools is a toolset that can be used to Collect, Send, Process and generate Reports for Netflow data flows and provides an API for developing custom features and applications. Flow Tools is hosted at .
  • Flowscan is more of a visualization tool that analyzes and reports Netflow data and can produce visual graphs that are in near real-time to see whats going on in your network. Flowscan can be deployed on a GNU/Linux or BSD system and uses some of the following packages in order to correctly collect and process flows: cflowd to as the flow collector, flowscan which is a perl script that makes up the software package itself ( FlowScan ) and is responsible for loading and executing reports and the last major component is RRDtool which is used to store all flow information in its database.
  • EHNT (which is pronounced ent ) is an acronym for Extreme Happy NetFlow Tool. This is a commandline tool that supports Netflow Version 5 only and provides reports for intervals between 1 min to 24 hrs and provides information about Ip Protocols, TCP/UDP ports and more.
  • (which stands for Berlekey Packet Filter Traffic collector) is a built on top of the BPF pseudo-device and libpcap for capturing IP traffic, including Source/Destination IP s Ports, number of transmitted/received bytes which are all stored in one compact form binary file.
  • Maji is an implementation of an IPFIX meter which is based on libtrace, a packet capturing and processing library. Maji seems to have an array of information per their website and the latest release was from 07/2011. One of the major benefits to maji is the custom templates you can develop with as many elements included into them as you want, and can be exported via Network over SCTP/TCP/UDP, SQLite database or the terminal.
  • cflowd is a tool that is made for analyzing Netflow enabled devices and includes modules for collecting, storing and analyzing netflow data. Apparently cflowd is no longer being supported per their website, and is directing users to use flow-tools with FlowScan in order to take advantage of cflowd and its modules.
  • AnonTool is more of an anonymization tool for netflow v5 v9 traces.
  • According to the sourceforge page, this project is no longer being developed or supported and was an open-source project that used NetFlow data to help detect and stop (Distributed) Denial of Service attacks. It is no longer support or being updated, so use at your own risk. Check out their Sourceforge page for more information and a download link.
  • pmGraph is a great open source tool for graphing and monitoring bandwidth using pmacct, which is a network monitoring and auditing tool. pmacct collects and monitors traffic using Netflow or Sflow on network devices (including firewalls, routers and switches) into a database and allows for analysis of that data using pmGraph. The software was developed by Aptivate staff and volunteers and looks to still be active.
  • sFlow toolkit is an open source software package the is used for analyzing sFlow data and can be used with other utilities including tcpdump, ntop and Snort for further analysis. sflowtool is the main component of the sFlow toolkit software and is a command-line utility that gives you the ability to view network traffic devices in real-time and interface with other software packages for mapping out graphical images of IP flow. sflowtool is also available for windows as well per their website .
  • NDSAD, which stands for NetUP s Data Stream Accounting Daemon, was developed by NetUP as a tool to capture packets and generate Netflow v5 data streams and was specifically used for ISP billing purposes. The software still seems to be supported as well.
  • NFsen, which is short for N et f low Sen sor, is a web-based front-end tool for nfdump to present the user a nice graphical image of all the data nfdump pumps out. You have the ability to generate reports of your netflow data with information including Flows, Packets and bytes using RRD database tool, as well as setup alerts and view historical data. nfsen project is still very active and can be downloaded from its Sourceforge page here and runs on any Unix/Linux systems. You ll need PHP, PERL (along with Perl Mail::Header and Mail::Internet modules), RRD Tools module and Nfdump tools installed on your system in order to use it correctly.

  • If your not convinced that you ve found any Open Source Netflow Analyzers that will suite your needs, due to either your skill level or understanding of Unix/Linux systems, you can always try one of these Free netflow software packages that we ve recently reviewed that will work for Windows systems.

    Most, if not all those downloads are free and can be setup and used very quickly some of them also offer pro versions of the software that can be had for very little investment. Check them out and let us know what you think.
