Hello, I've been trying to run ngsplot for a new ChIP-seq experiment, but I keep getting flat lines and empty heatmaps even when I use mulitple different input peak files. I re-ran the same code with the files from our older ChIP-seq experiment peak files and those work fine. Anyone have any ideas about why this might be happening?

My code: ngs.plot.r -G mm9 -R bed -C config.txt -O outputfilename

config.txt file: K8a_R1.nodups.bam inputfile “K8a” K8b_R1.nodups.bam inputfile “K8b”

First few lines of input file:
