sample_gap_splice {movementsync}

Randomly create matching segments from a splicing table without overlaps

Description

Works by randomly varying the gaps between segments assuming that the gap number follow a Poisson process with rate given by the average sample gap length in the input splice. Durations of segments remain the same.

Usage

sample_gap_splice(splicing_dfr, v, num_splices, rejection_list = list())

Arguments

splicing_dfr

Splice object.

v

View object.

num_splices

number of random splices to generate.

rejection_list

list of Splice objects for rejection.

Details

Uses rejection sampling to avoid overlaps with the input segments and additional segments from a list of splices.

Value

list of splicing data.frames.
