Normalize intervals to a fixed size

This function normalizes intervals by computing their centers and then expanding them to a fixed size, while ensuring they don't cross chromosome boundaries.

gintervals.normalize(intervals = NULL, size = NULL, intervals.set.out = NULL)

Arguments

intervals

intervals set

size

target size for normalized intervals (must be positive integer)

intervals.set.out

intervals set name where the function result is saved. If NULL, the result is returned to the user.

Value

Normalized intervals set with fixed size, or NULL if result is saved to intervals.set.out
