This program generates SICHO lattice chains suitable for the MONSSTER program. It is used by the package SICHO.pm but may also be used independently.
The program options are as follows: Either -p or -n are required to generate a chain from a PDB file or a completely random chain with the given number of residues, respectively. An offset for the generated chain can be set with -o. Alternatively the chain will be centered at the origin if -center is given. For random chains the overall grid size is important to limit the extension of the chain. It has to be less or equal than the setting in the MONSSTER program and can be changed with -g.
If a subset of residues is specified with the -l option, a random chain will be generated for these residues within the template for the protein surrounding taken from the PDB file.
Finally, a specific random seed may be given with -seed for test purposes to reproduce the same random chains.
