HiCOPS

Computational framework for scalable acceleration of database peptide search on supercomputers

db_prep

Command line tool that separates coarse-grained peptide sequence clusters of the specified range of peptide sequence lengths from a peptide sequence database (FASTA format). The output .pep files are directly used by the HiCOPS for database constructions and processing.

General Syntax
