NAME

SYNOPSIS

map_db [-n] filename | "filename libtype"  

DESCRIPTION

map_db filename reads the sequence database in filename and produce a new file filename.xin with the offset information necessary for efficient memory mapping.

The programs in fasta version 32t08 can use memory mapped i/o to load sequence database files and read them efficiently. Memory mapping is used only if a ".xin" file is available. The ".xin" file is created by map_db.

In addition to map_db, list_db is available to display the database size, etc, and set of offsets calculated by map_db.
