   3 =head1 NAME
   4
   5 bp_index.pl - indexes files for use by bp_fetch.pl
   6
   7 =head1 SYNOPSIS
   8
   9 bp_index.pl index_name file1 file2 etc.
  10
  11 =head1 DESCRIPTION
  12
  13 bp_index.pl builds a bioperl index for the sequence files given in the
  14 argument list, under the index name. For example
  15
  16    bp_index.pl nrdb /data/nrdb/nrdb.fasta
  17
  18 would build an index called 'nrdb' as the index name for the file
  19 nrdb.fasta, and
  20
  21    bp_index.pl -fmt EMBL swiss /data/swiss/*.dat
  22
  23 would build an index called swiss for all the files in /data/swiss
  24 which end in .dat which are in EMBL format.
  25
  26 The indexes are built using the Bio/Index/* modules, in particular,
  27 Bio::Index::EMBL and the Bio::Index::Fasta modules. Any script which
  28 uses these modules can use the index. A good example script is bp_fetch
  29 which fetches sequences and pipes them to STDOUT, for example
  30
  31    bp_fetch swiss:ROA1_HUMAN
  32
  33 gets the ROA1_HUMAN sequence from the swiss index and writes it as
  34 fasta format on STDOUT.
  35
  36 =head1 OPTIONS
  37
  38   -fmt  <format>   - Fasta (default), swiss or EMBL
  39   -dir  <dir>      - directory where the index files are found
  40                      (overrides BIOPERL_INDEX environment variable)
  41
  42 Options for expert use
  43
  44   -type <db_type>  - DBM_file type.
  45                      (overrides BIOPERL_INDEX_TYPE environment variable)
  46   -v               - report every index addition (debugging)
  47
  48 =head1 ENVIRONMENT
  49
  50 bp_index and bp_fetch coordinate where the databases lie using the
  51 environment variable BIOPERL_INDEX. This can be overridden using the
  52 -dir option. There is no default value, so you must use the -dir option
  53 or set BIOPERL_INDEX.
  54
  55 The DB type is coordinated with BIOPERL_INDEX_TYPE which if it
  56 is not there, defaults to whatever the bioperl modules have installed,
  57 which itself defaults to SDBM_File.
  58
  59 =head1 USING IT YOURSELF
  60
  61 bp_index.pl is a script that drives the Index modules. If you want to
  62 use this script heavily in your work, if it is Perl based, it is
  63 almost certainly better to look at the code in this script and copy
  64 it across (probably you will be more likely to want to use the bp_fetch
  65 code).
  66
  67 =head1 EXTENDING IT
  68
  69 bp_index is just a wrapper around James Gilbert's excellent Index modules
  70 found in bioperl
