Essentially, you're removing them because you can't disambiguate whether the read came from a unique bead source versus PCR. IMO, I removed PCR dups based on start and stop alone, because PCR has an inherent error rate. As before, you can't tell whether the base-differences (mm) came from independent events, or PCR-error.
