generate_peak_gtf: Merge peak and generate gft

In jiang-junyao/IReNA: IReNA

Merge peak and generate gft

Description

Merge the peaks that are close to each other and modify the length of the peak to 2*(peak_half_width). Finally, return peaks related gtf file

Usage

generate_peak_gtf(peak, peak_half_width = 250)

Arguments

peak	data.frame, indicating peaks file. If you call peak for each sample separately, you need to combine these peaks firstly through cbind().
peak_half_width	numeric, indicating half of peak width

Value

return peaks related gtf file

Examples

load(system.file("extdata", "test_peak.rda", package = "IReNA"))
peaks <- test_peak[,c(1,2,3)]
gtf <- generate_gtf(peaks)

## Not run:
