Open Source Tcl Data Management Systems

Maxima is a computer algebra system comparable to commercial systems like Mathematica and Maple. It emphasizes symbolic mathematical computation: algebra, trigonometry, calculus, and much more. For example, Maxima solves x^2-r*x-s^2-r*s=0, giving the symbolic results [x=r+s, x=-s]. It can also calculate with exact integers and fractions, native floating-point, and high-precision big floats. Maxima has user-friendly front-ends, an online manual, plotting commands, and numerical libraries. It features its own programming language, and many users have contributed useful packages in various areas over the decades. It is GPL-licensed and largely written in Common Lisp. Executables can be downloaded for Windows, Mac, Linux, and Android; source code is also available. An active community maintains and extends the system. Website: https://maxima.sourceforge.io Additional add-on packages for Maxima can be found at: https://github.com/maxima-project-on-github/maxima-packages

PLplot is a cross-platform, scientific graphics plotting library that supports math symbols and human languages (via UTF-8 user input strings); plot capabilities for multiple non-interactive plot file formats and in multiple interactive environments; and bindings for multiple computer languages.

SaVi - simulate Starlink, Iridium, Globalstar, O3b, GPS, Galileo and other satellite constellations, modify them, or design your own. Requires Tcl/Tk and Unix libraries; 3D viewing option requires Geomview running on X Window.

The Open-Source PyMOL repository has been moved to github: https://github.com/schrodinger/pymol-open-source We still use the pymol-users mailing list here on sourceforge. Please subscribe for community support: https://pymol.org/maillist (Note: SourceForge email newsletter and special offers are optional and can be unchecked) The PyMOL community wiki has its own home: https://pymolwiki.org/

TkTable is a full-featured 2D table widget for Tk. It supports images, embedded windows, varying colors and fonts, and more. Also here is Vu, a Tk widget extension that includes a pie, dial, spinbox and more, and Tile, a themed widget set for Tk.

surfit is an open source and free gridding and contouring software. surfit can do interpolation/approximation of points, contours and surfaces, can take fault lines and trend surfaces into account, can use inequalities and other conditions. Supports a lo

enhancements and development for the Vis5d scientific visualization tool, a program to display volumetric datasets in 3+ dimensions.

OzGIS is an extensive mapping system for the analysis and display of geographically referenced data. Map data are downloaded from Census bureaux and map agencies or extracted from your own databases. The system can be used to to support management decisions associated with, for example, government planning, marketing, sales, site and personnel location, advertising and research. Systems for Windows, Mac and Ubuntu, source code, sample data files and manuals are included. DOWNLOAD to your Downloads directory and unzip to Downloads/OzGIS ; see the Files tab for installation instructions. See the installation manual or "OzGIS Installation" Youtube video for help with getting started. I am unable to show OzGIS to you, so suggest that you search for "OzGIS lloyd" on Youtube for demonstration videos or "OzGIS" on Pinterest for example maps. You can mail me at cleverco@users.sourceforge.net or use the Discussion tab or post a ticket for problems.

Tcl n-dimensional array processor

The Huygens Remote Manager is an open-source, efficient, multi-user web-based interface to the Huygens software by Scientific Volume Imaging (http://www.svi.nl/) for parallel batch deconvolutions.

SpecTcl is a Tcl/Tk based histogrammer suitable for analysis of nuclear physics data. SpecTcl is relatively easy to learn, and is based on top of a very open C++ histogramming class framework. SpecTcl has been developed under NSF grant PHY-9528844 and DOE grant DE-SC0000661 Note that as of July 2023, all future development and release packages will be occur at https://github.com/FRIBDAQ/SpecTcl

The 3D Slicer is freely available, open-source software for visualization, registration, segmentation, and quantification of medical image data. Follow the link for more info: http://slicer.org

CAVOR is an engine for building apps that involve both graphic and text/numeric data. Primarily GIS is the initial focus, but consider also CAD, CASE, project management (eg PERT charts), and others. Built-in scripting, C API, also supports Tcl and Java.

The Graphical Display and Analysis Tool (GDAT) is a flexible and extensible data graphing program suitable for engineering applications. It can display and measure waveforms (e.g., rise time), and it can be extended through a plugin architecture.

GPLconx is an educational visualization tool that allows exploration of lines and conic sections in three models of 2-D hyperbolic geometry.

Histo produces histograms from the unix commandline. It is a program I wrote after I got tired of the limits of unix command line histograms.

ActiveGEM contains a set of perl/Tk graphical interfaces for the GEMPAK meteorological diagnostics and plotting package. These research-oriented interfaces provide easy access to low-level GEMPAK functions and allow for the maximum possible flexibility.

MSDViewer (My Schematic Drawer and Viewer) is a schema editor using a simple text file as input. Requires tcl/tk (>8.4) and Iwidgets (>4). should work on every platform supported by tcl/tk. Output postscripts.

The aim of this project is to offer an image processing library dedicated to Mathematical Morphology
