#!/usr/bin/env python # Hamming distance analysis of SSCSs # # Author: Monika Heinzl, Johannes-Kepler University Linz (Austria) # Contact: monika.heinzl@edumail.at # # Takes at least one TABULAR file with tags before the alignment to the SSCS and optionally a second TABULAR file as input. # 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. # The tool can run on a certain number of processors, which can be defined by the user. # USAGE: python HDnew6_1Plot_FINAL.py --inputFile filename --inputName1 filename
