From chemistry-request@ccl.net Tue Apr 23 12:03:27 1991 Date: Tue, 23 Apr 91 10:08:30 CDT From: Chris Parr Subject: Protein Ribbon Graphics To: Computational Chemistry List Status: R Dr. Ravishankar, another public domain package you might investigate is one by Professor Gareth Chelvanayagam called PASS; the acronym is Protein AnalysiS System. It was written in Turbo C for MS DOS machines and uses data in the Brookhaven format. The system is described in "PASS: Simple molecular graphics system for personal computers", J. Mol. Graphics (8) 207-210 (December 1990) including 5 color plates. When I requested a reprint, Prof. Chelvanayagam kindly included the program on an included diskette. However, his address is not that given in the byline of the article but rather Department of Biocomputing, European Molecular Biology Laboratory Postfach 10.2209, D-6900 Heidelberg, [West] Germany. The program will draw proteins in many representations including ribbon backbones. It requires an adapter compatible with EGA since it uses the EGA's second screen (256K versions only) for smooth animation. Happy viewing. - Chris Parr, University of Texas at Dallas P.O.Box 830688 M/S JO 3.2 Richardson, TX 75083-0688 U.S.A. Phone: 214/690-2231 BBS: 214/690-2168 (2400/8/N/1) BITNET: PARR@UTDALLAS
