MarkDuplicates has different duplication metrics than EstimateLibraryComplexity

    Hi Ravi Mandla, we would expect some differences in these metrics because the tools do not work the same. MarkDuplicates uses alignment information to determine duplicates. EstimateLibraryComplexity determines duplicates from the bases of the reads, allowing for some error, ignoring the reference. Hopefully this helps clarify these differences for you!
