I'm a bit confused about some of the output of GATK's DepthOfCoverage script. In the *.GATK.covdepth.sample_summary, what does the "total" column signify? Is it the total number of base pairs in the data? Because my raw read data has ~37.2 billion bp. However, GATK reports over 92 billion bp. Does the 'total' mean something else, or will I have to rerun the DepthofCoverage script?
Thanks in advance!
