I am doing a ChIP-Seq analysis on a small dataset of 6 samples (Wild-type and knockout having 3 replicates each). I wanted to run a Fisher exact test using bedtools. My bed files are all sorted. But I am getting this error.
Error: Sorted input specified, but the file /Users/xxx/narrowPeak/531-sorted.bed has the following record with a different sort order than the genomeFile /Applications/bedtools2/genomes/mouse.mm9.genome
What does this mean and how do I fix this ?
