SplitStrelkaSBSVCF

An in-memory data frame containing a Strelka VCF file contents.

vcf.df

The maximum difference of VAF, default value is 0.02.

SBSs are single base substitutions,
e.g. C&gt;T, A&gt;G,.... DBSs are double base substitutions,
e.g. CC&gt;TT, AT&gt;GG, ... Variants involving &gt; 2 consecutive
bases are rare, so this function just records them. These
would be variants such ATG&gt;CCT, AGAT&gt;TCTA, ...

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" catalogs
of mutational spectra or signatures.
