DepthOfCoverage interval_summary +1 on the start position of each intervals
When I check the coordinates of intervals given by DepthOfCoverage "*.interval_summary" file, I found that it tried to add one on the start position of each intervals. For example, the original coordinates in my .bed interval file is 3669022-3669474, then the DOC will give 3669023-3669474, only the start position, not the end one, actually.
I am not sure whether this is caused by "start from 0" or "start from 1" problem, because I have no idea about the coordinates in my original bed files start from 1 or start from 0.
I just worry does GATK DOC will miss one base for each interval?
