     - Higher relative differences occur either due to low total HDs and/or larger absolute differences, both things that indicate that 2 tags were originally the same tag.
     - A relative difference of 1 means that one part of the tags is identical. Since it is very unlikely that by chance two different tags have a HD of 0 between one of their parts, the HDs in the other part are probably artificially introduced (chimeric reads).
