Bio::Community::IO::Driver::gaas - Driver to read and write files in the GAAS format


   my $in = Bio::Community::IO->new( -file => 'gaas_communities.txt', -format => 'gaas' );

   # See Bio::Community::IO for more information


This Bio::Community::IO::Driver::gaas driver reads and writes files in the format generated by GAAS (http://sourceforge.net/projects/gaas/). GAAS creates one such file per community. Here is an example:

  # tax_name    tax_id  rel_abund
  Streptococcus pyogenes phage 315.1    198538  0.791035649011735
  Goatpox virus Pellor  376852  0.196094208626593
  Lumpy skin disease virus NI-2490      376849  0.0128701423616715

For each Bio::Community::Member $member generated from a GAAS file, $member->id() contains the content of the tax_id field, while $member->desc() reflects the tax_name field.

Note that GAAS format does not include counts for the community members but relative abundances only. Thus, the get_members_count() method of the Bio::Community objects generated using this driver is a relative abundance (a decimal number) instead of the usual integers used for counts.
