Library to control radio transceivers and receivers
The Hamlib project's purpose is to develop flexible and portable shared libraries that offer a standardized API to control any radio oriented equipment through a computer interface.
a tool for segmenting, labeling and transcribing speech
Project moved to https://github.com/owfs/owfs/
Please note that OWFS source code, and all Issue/Tickets/merge requests have now been moved to https://github.com/owfs/owfs/. Developer mailing lists will still be kept at Sourceforge. ---- OWFS -- 1-Wire file system. Use the Dallas 1-Wire and iButton chips with standard filesystem commands. Create temperature loggers. Monitor everything. OWHTTPD -- same system, only used as a light weight web server. OWFS is also ported to embedded routers, Mac OSX and Windows. Basically you can use these inexpensive little sensors and other chips with very simple wiring to sense and control the physical environment. The interface is very flexible -- everything from a web browser, to read and writing directly to the chip's "file" to integrating with your programs -- even over the internet. There is a growing number of 1-wire sensors: temperature, voltage, humidity, light, ultraviolet, pressure, thermisters, thermocouples, programmable microcontrollers, relays, lights, LCD panels, etc
A fully developed set of DNA sequence assembly (Gap4 and Gap5), editing and analysis tools (Spin) for Unix, Linux, MacOSX and MS Windows.
System dynamics program with additional features for economics
Minsky enables the simulation of models (particularly from economics) defined in terms of coupled ordinary differential equations. The models are defined using a drawing canvas (rather like VisSim), and a double entry bookkeeping system known as a Godley table.
Earth orbits and coverage display in 3D on your laptop.
SaVi - simulate Iridium, Globalstar, O3b, Sirius Radio, GPS, Galileo and other satellite constellations, modify them, or design your own. Uses Tcl/Tk and Unix libraries; 3D viewing option requires Geomview running on X Window.
EMU is a collection of software tools for the creation, manipulation and analysis of speech databases. At the core of EMU is a database search engine which allows queries based on the sequential and hierarchical structure of the annotations.
TkGate is a event driven digital circuit simulator with a tcl/tk-based graphical editor. TkGate supports a wide range of primitive circuit elements as well as user-defined modules for hierarchical design.
A library for multiple precision math - arbitrarily large numbers - in TCL. Based on the original mpexpr library from Tom Poindexter.
Tcl binding to VISA API
Tcl binding to VISA (Virtual Instrument Software Architecture) API. It is linked to Tcl as a standard extension following Tcl Extension Architecture (TEA) conventions. See VISA specs. on IVI Foundation page: http://www.ivifoundation.org/specifications/default.aspx TEA specs. can be found here: http://www.tcl.tk/doc/tea/
AGTK is a suite of software components for building tools for annotating linguistic signals, time-series data which documents any kind of linguistic behavior (e.g. audio, video). The internal data structures are based on annotation graphs.
LensOSX: the light, efficient network simulator
Lens is the light, efficient network simulator, written by Doug Rohde. LensOSX is a native MacOSX port of Lens that runs on MacOSX 10.5 or higher, created by Harm Brouwer, Daniel de Kok and Hartmut Fitz.

vmdStore provides a user-friendly interface to free install VMD plugins. vmdStore also helps you keeping the plugins always updated. Minimum Requirements Operating System: macOS, Linux, or Windows Visual Molecular Dynamics (VMD) 1.9.3 or later
Weighted Implementation of Suboptimal Paths (WISP)
Allostery can occur by way of subtle cooperation among protein residues (e.g., amino acids) even in the absence of large conformational shifts. Dynamical network analysis has been used to model this cooperation, helping to computationally explain how binding to an allosteric site can impact the behavior of a primary site often many angstroms away. Traditionally, computational efforts have focused on the most optimal path of correlated motions leading from the allosteric to the primary active site. We present a program called Weighted Implementation of Suboptimal Paths (WISP) capable of rapidly identifying additional suboptimal pathways that may also play important roles in the transmission of allosteric signals. Aside from providing signal redundancy, suboptimal paths traverse residues that, if disrupted through pharmacological or mutational means, could modulate the allosteric regulation of important drug targets.
