Converets Cambridge Structural Database .dat files to PDB format. Program is in ANSI C (i.e., will not work with native SUN compiler). The programm works only if the .dat file includes all crystallographic data, else you will have to edit the .dat file and delete the parts where those data are missing,(you can also, modify the code). If people are interested, I can also provide the executable files, dos or windows, (e-mail) See you Francois Savary, University of Geneva, Departement of Physical Chemistry 30, quai Ernest Ansermet, CH-1211 Geneva 4, Switzerland +4122 702 65 32 (phone), +4122 702 65 18 (fax) savary@sc2a.unige.ch (e-mail)
