centerGRangesAtMax: Centers query GRanges at maximum signal in prof_dt.

In seqsetvis: Set Based Visualizations for Next-Gen Sequencing Data

Description

Centers query GRanges at maximum signal in prof_dt.

Usage

centerGRangesAtMax(prof_dt, qgr, x_ = "x", y_ = "y", by_ = "id", width = 1)

Arguments

prof_dt	a GRanges or data.table as returned by ssvFetch*.
qgr	the GRanges used to query ssvFetch* as the qgr argument.
x_	positional variable. Should almost always be the default, "x".
y_	the signal value variable. Likely the default value of "y" but could be "y_norm" if append_ynorm was applied to data.
by_	region identifier variable. Should almost always be the default, "id".
width	Desired width of final regions. Default is 1.

Value

a GRanges with same mcols as qgr that has been centered based on signal in prof_dt and with regions of specified width.

Examples

centerGRangesAtMax(CTCF_in_10a_profiles_dt, CTCF_in_10a_overlaps_gr)
centerGRangesAtMax(CTCF_in_10a_profiles_gr, CTCF_in_10a_overlaps_gr)
