read_hexamer.py
+++++++++++++++++++++

Calculate hexamer (6mer) frequency. If ‘-r’ was specified, hexamer frequency
is also calculated for the reference genome. If ‘-g’ was provided, hexamer
frequency is also calculated for the mRNA sequences.

Inputs
++++++++++++++

Input reads file
    Read sequences in fasta or fastq format.

Reference Genome
    Reference genome sequence in fasta format.

Reference Gene
    Reference mRNA sequences in fasta format.


Outputs
++++++++++++++

Tabular file of hexamer frequences in for each input.
