-# The program produces a plot which shows a histogram of Hamming distances separated after family sizes,
-# a family size distribution separated after Hamming distances for all (sample_size=0) or a given sample of SSCSs or SSCSs, which form a DCS.
-# In additon, the tool produces HD and FSD plots for the difference between the HDs of both parts of the tags and for the chimeric reads
-# and finally a CSV file with the data of the plots.
-# It is also possible to perform the HD analysis with shortened tags with given sizes as input.

     - 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).

 These calculations were repeated, but starting with the second half in the first step to find all possible chimeras in the data (HD b and HD  For simplicity we used the maximum value between the delta values in the end.
