This package provides an extensive toolset for the characterization and visualization of a wide range of mutational patterns from base substitution catalogues. These patterns include: mutational signatures, transcriptional strand bias, genomic distribution and association with genomic features.
The package provides functionalities for both extracting mutational signatures de novo and inferring the contribution of previously identified mutational signatures. Furthermore, MutationalPatterns allows for easy exploration and visualization of other types of patterns such as transcriptional strand asymmetry, genomic distribution and associations with (publically available) annotations such as chromatin organization. In addition to identification of active mutation-inducing processes, this approach also allows for determining the involvement of specific DNA repair pathways. For example, presence of a transcriptional strand bias in genic regions may indicate activity of transcription coupled repair.
