I have about 57 BED files with various overlapping intervals between them. I would like to merge them all, like with multiple intersect from BEDTools, but average the score associated with the overlap across the files. I see there is a function in MergeBED to add an additional column to average the score from overlapping intervals, but I don't see this for 'multiple intersect' for multiple files.
The caveat is my limited programming knowledge, so I use the Galaxy server. Is there a way to do this?
