Dear netters, As it seems that the program I made a few months ago is of some interest for lots of people and that the first version was not 100 % error free (this version is surely also not but still a bit better). I have corrected the code so that the program now reads the fdat file and produces PDB files (with .ent extension) up to 250 atoms it also makes the connectivity matrix so you can directly read it to HyperChem 3.0, or any program that lakes bond making the files produced are made with the refcode in the fdat file with 6 up to 8 characters if necesserary. The program is still not using every informations that are avalaible in the fdat file, sorry I'm not a cristallographer. The program is in ansi C but should easy to transcript for Sun workstations (I have tested it yet on SGI and PC's) when you run the program, it will aks you the fdat filename and will then automatically create pdbfiles in the directory you have started the program. Hope it will help Francois Savary -------------------------------------------------------------- Francois Savary Department of Physical Chemistry University of Geneva 30, quai Ernest-Ansermet CH-1211 Geneva 4 phone : +4122 702 65 32 fax : +4122 702 65 18 e-mail : savary@sc2a.unige.ch --------------------------------------------------------------
