chess-3.0 for Linux chess-3.0 for MacOS X (BSD) chess-3.0 for Solaris     scripting tutorial (PDF, 710 Kb) scripting tutorial (gzipped postscript, 202 Kb)

Note: the scripting tutorial is not quite up-to-date. This guide may serve as a starter: help on recent keywords is available on-line as outlined in the tutorial. We are working on a new tutorial for this version.

1. Create 2 new directories /usr/local/chess/bin and /usr/local/chess/tdb.
2. Download CHESS in /usr/local/chess/bin and, eventually, make CHESS executable with chmod a+x.
3. make a symbolic link between this executable and /usr/local/bin/chess
4. Download one or several databases (from here) in /usr/local/chess/tdb. Note that CHESS looks for /usr/local/chess/tdb/chess.tdb in absence of other filename specifications in the script.

CHESS produces simple output files according to the format X, Y1, Y2,... which are readily read with any graphical software. Reaction path results are readily displayed with either JPlot or Gnuplot (both GNU-ware and freely available).

Your feedback is appreciated! Please send us comments, corrections, shortcomings or other remarks to our email address, because it will help us to update the model faster and more efficiently.
