I just can't get Aggregate Datapoints phastCons to work. I have a bed/interval file, I set the metadata to say it's from hg18 so I can choose phastCons in the Aggregate Datapoints tool and then I run it.
But the values I get back are all "nan". Average, min, max, all "nan".
The metadata for the bed file puts the right values for the Chrom, Start, and End columns, but it also specifies the strand column. I can't tick off "strand" and it keeps saying that column 1 (which is my Chrom column) is the strand column. I don't know if it has anything to do with this (but I suppose phastCons doesn't use the strand column for anything?).
