I am using a ChIP-Seq data from mod-ENCODE website. The file format that I have downloaded from this website is based on gff3. The 6th column of this file (pasted bellow) belongs to score which ranges from + to - score. First of all I am not sure what is this score about? Is it the summit confidence score in ChIP-Seq file? If this is correct, should I consider + scores as high confidence score?
