recognized by getBSgenome
. Only required if
subject is GenomicRanges
or
RangedSummarizedExperiment
or if bg is set
to "genome"Either returns a SummarizedExperiment with a sparse matrix with
values set to TRUE for a match (if out == 'matches'), a
SummarizedExperiment with a matches matrix as well as matrices with the
maximum motif score and total motif counts (if out == 'scores'), or a
GenomicRangesList
or a list of
IRangesList
with all the positions of matches
(if out == 'positions')
Background nucleotide frequencies can be set to "subject" to use the subject sequences or ranges for computing the nucleotide frequencies, "genome" for using the genomice frequencies (in which case a genome must be specified), "even" for using 0.25 for each base, or a numeric vector with A, C, G, and T frequencies.
