Filters lowly expressed peaks from down-stream analyses
filterConsensus(
cp,
filter.method = "custom",
library.threshold = 2,
cpm.threshold = 1
)
consensus peak matrix, with unique ids at rownames.
filtering method for low expressed peaks
number of libraries a peak occurs so that it is not filtered default set to 2
count per million threshold for not to filter a peak
returns differentially accessible peaks
