An enhanced version of SMMP—open-source software package for simulation of proteins

We describe a revised and updated version of the program package SMMP (Simple Molecular Mechanics for Proteins) [F. Eisenmenger, U.H.E. Hansmann, Sh. Hayryan, C.-K. Hu, Comput. Phys. Comm. 138 (2001) 192–212]. SMMP is an open-source FORTRAN package for molecular simulation of proteins within the standard geometry model. It is designed as a simple and inexpensive tool for researchers and students to become familiar with protein simulation techniques. This announcement describes the first major revision of this software package and its newly added features.Program summaryTitle of program:SMMPCatalogue identifier:ADOJ−v2−0Program summary URL:http://cpc.cs.qub.ac.uk/summaries/ADOJ_v2_0Program obtainable from: CPC Program Library, Queen's University of Belfast, N.
