Summary: Main data files and backing data for the analysis identifying 
positively selected codons.  This data and updates are available for 
download from here:  http://www.ebi.ac.uk/~greg/mammals/

Pol_sel_score.bed - one region per Ensembl gene analyzed, with a score corresponding to the negative log of an overall p-value for positive selection at that gene based on mammalian alignments.^M      Overall_dN_dS.bed - one region per Ensembl gene analyzed, with a score corresponding to the overall dN/dS at that gene based on mammalian alignments.^M        Sites.bedGraph - one value per codon analyzed, with a score corresponding to the signed sitewise likelihood ratio statistic for non-neutral selection. V
alues above zero indicate evidence for positive selection, values below zero ind
icate evidence for negative selection. The statistic is approximately chi-square
 distributed when the data is neutrally evolving.  The bedGraph file looks best 
 when displayed on UCSC the following track parameters:^M
 ??type=bigWig^M
 ??lineMark=0^M
 ??lineOnOff=on^M
 ??autoScale=off^M
 ??viewLimits=-20:10^M??minLimit=-20^M
 ??maxLimit=10^M??visibility=full^M
