'''Scientific computing''' is one of the areas where Tcl has had a good deal of uptake. ** See Also ** [numerical analysis in Tcl]: [http://phaseit.net/claird/comp.programming/open_source_science.html%|%Cameron Laird's personal notes on open source for science]: [https://web.archive.org/web/20070315220013/http://www-128.ibm.com/developerworks/linux/library/l-osbio.html%|%pen source in the biosciences], [Cameron Laird], 2002-11-01: ----- [http://www.cwp.mines.edu/cwpcodes/%|%Seismic Unix] (SU) is a free seismic reflection and signal processing package available from the Center for Wave Phenomena, Colorado School of Mines, having a command-line-driven interface. http://www.henrythorson.com/interface.htm%|%TKSU is a graphical user interface to SU, providing the ability to interactively build a processing flow out of SU modules, set values for module parameters from menus, and create a shell script to execute the processing flow. Although developed specifically for the SU package, TKSU is an independent application that can manage any set of programs that follows the command-line convention of the SU package (the "parfile" convention).
