Analysis and visualization of experimentally elucidated mutational
signatures -- the kind of analysis and visualization in Boot et al.,
"In-depth characterization of the cisplatin mutational signature in
human cell lines and in esophageal and liver tumors", Genome Research 2018,
<doi:10.1101/gr.230219.117> and
"Characterization of colibactin-associated mutational signature in an
Asian oral squamous cell carcinoma and in other mucosal tumor types",
Genome Research 2020 <doi:10.1101/gr.255620.119>.
'ICAMS' stands for In-depth Characterization
and Analysis of Mutational Signatures. 'ICAMS' has functions to read in
variant call files (VCFs) and to collate the corresponding catalogs of
mutational spectra and to analyze and plot catalogs of mutational spectra
and signatures. Handles both "counts-based" and "density-based" (i.e.
representation as mutations per megabase) mutational spectra or signatures.

GetStrandedKmerCounts function

<dl><dt>k</dt>
<dd>Length of k-mers (k&gt;=2)</dd>
<dt>ref.genome</dt>
<dd>A <code>ref.genome</code> argument as described in
<code>ICAMS</code>.</dd>
<dt>stranded.ranges</dt>
<dd>A keyed data table which has stranded ranges
information. It has four columns: chrom, start, end and strand. It should
use one-based coordinate system.</dd>
<dt>filter.path</dt>
<dd>If given, homopolymers will be masked from
genome(sequence). Only simple repeat masking is accepted now.</dd>
<dt>verbose</dt>
<dd>If <code>TRUE</code> generate progress messages.</dd></dl>
