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.
