Binding Site Annotation

Using ChIPseeker (R)

library(ChIPseeker)
library(TxDb.Hsapiens.UCSC.hg38.knownGene)

txdb <- TxDb.Hsapiens.UCSC.hg38.knownGene

peaks <- readPeakFile('peaks.bed')
anno <- annotatePeak(peaks, TxDb = txdb)

plotAnnoPie(anno)

Using BEDTools

# Annotate to UTRs
bedtools intersect -a peaks.bed -b 3utr.bed -wa -wb > peaks_3utr.bed

Python Annotation

import pandas as pd

def annotate_peaks(peaks_bed, annotation_gtf):
    '''Annotate peaks to genomic features'''
    # Load peaks and annotations
    # Intersect and categorize
    pass
