Extend GRanges from thick regions and trim to fixed width

Extends each region in a `GRanges` object based on its `thick` metadata, symmetrically by a specified distance, then trims out-of-bound ranges and keeps only those with the expected fixed width.

Usage

plc_extend_fromthick(tc_gr, ext_dis = 200)

Arguments

tc_gr

A `GRanges` object with a `thick` metadata column (of type `IRanges`).

ext_dis

An integer specifying how many bases to extend on each side of the thick region. Default is 200.

Value

A trimmed `GRanges` object with fixed-width ranges.
