Function to obtain a mask given a genome available as a BSgenome. The mask returned is the merge of all the active masks in the BSgenome.
Since it uses characterToBSGenome, the genome can be either a BSgenome object or a character string uniquely identifying the a BSgenome object installed.
Usage
getMask(genome)
Arguments
genome
the genome from where the mask will be extracted. It can be either a BSgenome object or a character string uniquely identifying a BSgenome object installed (e.g. "hg19", "mm10", ...)
Value
A GRanges object with the genomic regions to be masked out
