NAME
       map_db -	read a FASTA (0), GENBANK flat file (1)	PIR/VMS	(5) or GCG bi-
       nary (6)	sequence database and produce the offsets necessary for	 effi-
       cient memory mapping.

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	 effi-
       cient 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.

OPTIONS
       -n     Read file	as DNA database.
