NAME

       bp_index.pl - indexes files for use by bp_fetch.pl

SYNOPSIS

       bp_index.pl index_name file1 file2 etc.

DESCRIPTION

       bp_index.pl builds a bioperl index for the sequence files given in the argument list, under the index
       name. For example

          bp_index.pl nrdb /data/nrdb/nrdb.fasta

       would build an index called 'nrdb' as the index name for the file nrdb.fasta, and

          bp_index.pl -fmt EMBL swiss /data/swiss/*.dat

       would build an index called swiss for all the files in /data/swiss which end in .dat which are in EMBL
       format.

       The indexes are built using the Bio/Index/* modules, in particular, Bio::Index::EMBL and the
       Bio::Index::Fasta modules. Any script which uses these modules can use the index. A good example script
       is bp_fetch which fetches sequences and pipes them to STDOUT, for example

          bp_fetch swiss:ROA1_HUMAN

       gets the ROA1_HUMAN sequence from the swiss index and writes it as fasta format on STDOUT.

OPTIONS

         -fmt  <format>   - Fasta (default), swiss or EMBL
         -dir  <dir>      - directory where the index files are found
                            (overrides BIOPERL_INDEX environment variable)

       Options for expert use

         -type <db_type>  - DBM_file type.
                            (overrides BIOPERL_INDEX_TYPE environment variable)
         -v               - report every index addition (debugging)

ENVIRONMENT

       bp_index and bp_fetch coordinate where the databases lie using the enviroment variable BIOPERL_INDEX.
       This can be overridden using the -dir option. There is no default value, so you must use the -dir option
       or set BIOPERL_INDEX.

       The DB type is coordinated with BIOPERL_INDEX_TYPE which if it is not there, defaults to whatever the
       bioperl modules have installed, which itself defaults to SDBM_File.

USING IT YOURSELF

       bp_index.pl is a script that drives the Index modules. If you want to use this script heavily in your
       work, if it is Perl based, it is almost certainly better to look at the code in this script and copy it
       across (probably you will be more likely to want to use the bp_fetch code).

EXTENDING IT

       bp_index is just a wrapper around James Gilbert's excellent Index modules found in bioperl
