<p>I want to  have a bigwig file converted into gff after having the genome coordinates and genome annotation files converted from Hg19 to Hg18. One way, would be to convert bigwig into BED, use the liftover tool and then have the BED file converted into gff. Could someone please suggest a method to convert bigwig to BED, nothing available on the net.</p>
