#  The purpose of this script is to read-in a FASTQ file line-
#  by-line and record every kmer found as defined by the user.
#  All kmers are recorded and quantified, with several metrics
#  reported after the FASTQ has been fully transversed.

#  Usage:     perl kmer_counting_in_FASTQ.pl /
#             sample_file.FASTQ
#             kmer

#  Example:   perl kmer_counting_in_FASTQ.pl 01928_1.fastq 7
