GNU PSPP is a program for the statistical analysis of sampled data. It is a Free replacement for the proprietary program SPSS, and appears very similar to it with a few exceptions. The most important of these exceptions are, that there are no “time bombs”; your copy of PSPP will not “expire” or deliberately stop working in the future. Neither are there any artificial limits on the number of cases or variables which you can use. There are no additional packages to purchase in order to get “advanced” functions; all functionality that PSPP currently supports is in the core package.
      PSPP is a stable and reliable application. It can perform descriptive statistics, T-tests, anova, linear and logistic regression, measures of association, cluster analysis, reliability and factor analysis, non-parametric tests and more. Its backend is designed to perform its analyses as fast as possible, regardless of the size of the input data. You can use PSPP with its graphical interface or the more traditional syntax commands.
      A brief list of some of PSPP's features.
      
        Support for over 1 billion cases
        Support for over 1 billion variables
        Syntax and data files which are compatible with those of SPSS
        A choice of terminal or graphical user interface
        A choice of text, postscript, pdf, opendocument, html or TeX output formats
        Inter-operability with: LibreOffice, Apache OpenOffice, Gnumeric and other free software
        Easy data import from spreadsheets, text files and database sources
        The capability to open, analyse and edit two or more datasets concurrently
        A user interface supporting all common character sets
        The user interface has been translated to multiple languages
        Very fast statistical procedures, even on very large data sets
        No license fees and no expiration period
        No unethical “end user license agreements”
        A fully indexed user manual
        Freedom ensured; It is licensed under the GPLv3 or later
        Portability; Runs on many different computers and many different operating systems
      
      PSPP is particularly aimed at statisticians, social scientists and students requiring fast convenient analysis of sampled data.
      The Flatpak for PSPP includes graphical and command-line interfaces.  To use the command-line interface, run: flatpak run --command=pspp org.gnu.pspp.

     PyMOL is one of a few open-source visualization tools available
     for use in structural biology. The Py portion of the software's
     name refers to the fact that it extends, and is extensible by the
     Python programming language.
   
      
     PyMOL has the ability to load, manipulate and visualize molecules
     from a variety of formats and sources.  The program can easily be
     controlled using a menu-driven GUI, or from a large number of
     commands and/or scripts.  A built-in raytracer is available to
     generate high-quality images of the views generated in the GL
     portion of the GUI.
   
      
     PyMOL uses OpenGL Extension Wrangler Library (GLEW) and Freeglut,
     and can solve Poisson–Boltzmann equations using the Adaptive
     Poisson Boltzmann Solver (apbs).
  
      
    Install this application to view, analyze, and prepare graphics
    images of proteins and experimental strucural data
    (e.g. crystallographic, NMR and electron microscopy based).

        Spot the Unknown: As a structured understanding of the data emerges, identify unknowns and anomalies
      
      Squey can be used for many different purposes, such as:
      
        BI and Big Data: Bootstrap initial understanding of complex datasets and deep dive where necessary to design accurate data processing
        Cybersecurity: Detect weak signals such as attacks and data leaks
        IT troubleshooting: Resolve network issues and improve application performance
        Machine Learning: Design training dataset to fulfill targeted improvements of Machine Learning models

      wxMaxima is a graphical user interface for the computer algebra system Maxima:
      a program that solves mathematical problems by manipulating
      equations (and outputting the resulting formula), instead of just
      calculating a number. wxMaxima eases the use of Maxima by making
      most of its commands available through a menu system and by
      providing input dialogs for commands that require more than one
      argument. It also implements its own display engine that outputs
      mathematical symbols directly instead of depicting them with
      ASCII characters.
    
      
      wxMaxima also features 2D and 3D inline plots, simple animations,
      mixing of text and mathematical calculations to create documents,
      exporting of input and output to TeX, document structuring and a
      browser for Maxima's manual including command index and full text
      searching.

SciDAVis is a free interactive application aimed at data analysis and publication-quality plotting. It combines a shallow learning curve and an intuitive, easy-to-use graphical user interface with powerful features such as scriptability and extensibility. SciDAVis runs on GNU/Linux, Windows and MacOS X; possibly also on other platforms like *BSD, although this is untested.SciDAVis is similar in its field of application to proprietary Windows applications like Origin and SigmaPlot as well as free applications like QtiPlot, Labplot and Gnuplot.What sets SciDAVis apart from the above is its emphasis on providing a friendly and open environment (in the software as well as the project) for new and experienced users alike. Particularly, this means that we will try to provide good documentation on all levels, ranging from user’s manual over tutorials down to and including documentation of the internal APIs We encourage users to share their experiences on our forums and on our mailing lists.More information, including screenshots, reviews, current contributors can be found on the SourceForge project webpage.
