Histogram-all-columns-compare-all_vs_high-bars.pl

Program will take data on two tab delimited files that contain the frequencies of codon usage in all genes or in highly expressed genes from each of the analyzed genomes ( and ). Data files must be tab delimited. Lines with "#" will be skipped. Both files should have the same amount of columns and use the same column names in similar order. First line in the file has to be commented and have the column titles.
Using these files it will construct three results files for each column. These results files will contain the number of genomes that present a codon usage that falls in each of the defined ranges. Each range is constructed based on the given values. Ranges start at value and make steps of size
Based on these results files, the script will produce a series of histogram plots comparing the distributions on each given file using GnuPlot. This script requires GnuPlot installed and in the path. It has been tested with version 5.2 of GnuPlot.
Plots will be saved in the "./histogram_All_vs_High" directory, unless another folder is specified a the end of the command line
