PECAAN Z-scores differ from DNAMasters

edgingtonn1	Hi, It seems that the Z-scores from PECAAN differ from the Z-scores from DNAMaster for a given gene, and for the same start sites. Any idea why? Both scores for the same gene start always seem to show the same trend, so it doesn't seem like a big issue– just a curiosity for now. Which one should be in the final annotation notes? We are going with the PECAAN ones since they are all imported into DNAMaster at once. Best, -Nick SCSU, New Haven CT

ClaireRinehart	Nick and Debbie, DNA master bases its z-scores on the raw scores of all possible open reading frames. PECAAN uses the open reading frames of candidates for all GeneMark and Glimmer called genes for the z-scores. Also, PECAAN uses double precision floating point calculations, which may cause slightly different results. Claire and Dex
