kViz is a simple bioinformatics tool for visualizing the dristibution of the k-mer coverage within a given set of sequencing reads.
Since kViz is written in Perl, you'll need Perl 5.6.0 or later installed in your machine.
Additionally you'll need the Template Toolkit module for Perl. You can install it using the CPAN Module by just typing the following in the command line:
$ sudo cpan Template
Within the kViz directory, execute in the command line the Perl script under the src folder with all three arguments.
$ perl src/kviz.pl <INPUT_FILE> <OUTPUT_FILE_PREFIX> <K-MER_SIZE>
<INPUT_FILE>: input fasta or fastq file containing read sequences
<OUTPUT_FILE_PREFIX>: the path to the output file without file format ending, e.g.: "data/kmer_coverage_file"
<K-MER_SIZE>: size of the created k-mers
kViz generates a HTML file with a histogram showing the k-mer coverge distribution. The histogram is generated using Google Charts Tools.
