New tools released to Galaxy Test at http://test.g2.bx.psu.edu. 1. Gene BED to Exon/Intron BED ("Convert Formats" tool set) - This tool is an enhancement to the old tool "Gene BED to Exon BED". It converts a UCSC gene bed format file to a list of bed format lines corresponding to requested features of each gene. The new feature is to convert gene bed lines to intron bed lines. And the interface is more user friendly. 2. yn00 ("PAML" tool set) - this tool finds the ratio of the number of non-synonymous substitutions per non-synonymous site (Ka) to the number of synonymous substitutions per synonymous site (Ks) for the alignments in the input file.
