GAAS (Genome relative Abundance and Average Size) is a bioinformatic tool to calculate accurate community composition and average genome size in metagenomes by using BLAST, advanced parsing of hits and correction of genome length bias.

Input database can now contain aminoacids. BLASTX is used in that case. Added a warning for metagenomes that have a number of sequences smaller than the desired bootstrap sample size. Fallback is to not do bootstrap on this metagenome. Fixed a bug that made GAAS crash when a sequence had a length of 0 bp. Fixed a bug in the way the hits are bootstrapped. Fixed a bug in a floating point calculation that lead to large roundoff error on the bootstrap estimates. Fixed a bug that made bootstrapped repetitions that resulted in no hits being kept being counted.
Implemented a bootstrap procedure to output confidence intervals on the relative abundance and average genome length estimates New dependency: Math::Round Perl module Fixed bug that prevented the graphing of relative abundance on a piechart when not using a taxonomy file
