Creates a .txt file from mutation data that can be used for mutational signatures analysis using the SigProfiler Assignment web application. Currently only supports SBS analysis i.e. snvs.

Usage

write_mutation_calling_file(
  mutation_data,
  project_name = "Example",
  project_genome = "GRCm38",
  output_path = NULL
)

Arguments

mutation_data

The object containing the mutation data. The output of import_mut_data() or import_vcf_data().

project_name

The name of the project. Default is "Example".

project_genome

The reference genome to use. (e.g., Human: GRCh38, Mouse mm10: GRCm38)

output_path

The path to save the output file. If NULL, files will be saved in the current working directory. Default is NULL.

Value

a .txt file that can be uploaded to the SigProfiler Assignment web application (https://cancer.sanger.ac.uk/signatures/assignment/) as a "Mutational calling file".

Details

Mutations will be be filtered for SNVs. Mutations flagged in filter_mut will be excluded from the output.

Examples

example_file <- system.file("extdata", "Example_files",
                            "example_mutation_data_filtered.rds",
                            package = "MutSeqR")
example_data <- readRDS(example_file)
temp_output <- tempdir()
write_mutation_calling_file(mutation_data = example_data,
                            project_name = "Example",
                            project_genome = "GRCm38",
                            output_path = temp_output)
