Protein Ribbon Graphics



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.
