Having created the EMBOSS indexes for this file, a database can then be defined in the file emboss.defaults as something like:
DB emrod [ type: N dbalias: emrod (see below) format: fasta method: emboss directory: /data/embl/fasta file: emrod.fasta indexdirectory: /data/embl/fasta/indexes ]The index file 'basename' given to dbxfasta must match the DB name in the definition. If not, then a 'dbalias' line must be given which specifies the basename of the indexes.
SET PAGESIZE 2048 SET CACHESIZE 200The above values are recommended for most systems. The PAGESIZE is a multiple of the size of disc pages the operating system buffers. The CACHESIZE is the number of disc pages dbxfasta is allowed to cache.
RES embl [ type: Index idlen: 15 acclen: 15 svlen: 20 keylen: 25 deslen: 25 orglen: 25 ]The length definitions are the maximum lengths of 'words' in the field being indexed. Longer words will be truncated to the value set.
