Technical Notes

The sources files are in WIG fixedStep format. Conversion into SGA was carried out with an ad hoc Perl script. In order to keep the SGA files reasonably compact, only positions with phyloP scores greater than a threshold value t were considered. The original real-valued scores were first dimished by t-1 and then rounded down to the nearest integer:
	  counts = int(phyoP_score-t+1)
	
The modified phyloP score is given in the count (5th) field of the SGA files.

Threshold value: 2.0
