NAMEmap_db - read a FASTA (0), GENBANK flat file (1) PIR/VMS (5) or GCG
binary (6) sequence database and produce the offsets necessary for
efficient memory mapping.
SYNOPSISmap_db [-n] filename | "filename libtype"
DESCRIPTIONmap_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.
