What it does
bedtools subtract searches for features in B that overlap A. If an overlapping feature is found in B, the overlapping portion is removed from A and the remaining portion of A is reported. If a feature in B overlaps all of a feature in A, the A feature will not be reported.
This tool is part of the bedtools package from the Quinlan laboratory.
