Get significant interactions from a GRangesList

Retrieves all significant interactions from the output of callInteractions.

getSignInteractions(gr_interactions)

Arguments

gr_interactions	GRangesList outputed by callInteractions.

Value

GRanges object with a list of significantly interacting regions.

Examples

data("ex_ciita_umi4c")
umi <- ex_ciita_umi4c
win_frags <- makeWindowFragments(umi, n_frags=8, sliding=1)

gr <- callInteractions(umi, ~condition, win_frags, padj_threshold = 0.01, zscore_threshold=2)
