### See Also

`read_vcfs_as_granges`, `mut_context`

### Examples

    ## See the 'read_vcfs_as_granges()' example for how we obtained the
    ## following data:
    vcfs <- readRDS(system.file("states/read_vcfs_as_granges_output.rds",
                    package="MutationalPatterns"))

    ## Load the corresponding reference genome.
    ref_genome <- "BSgenome.Hsapiens.UCSC.hg19"
    library(ref_genome, character.only = TRUE)

    type_context <- type_context(vcfs[[1]], ref_genome)
