HOMER: findMotifsGenome.pl error message
 
Hi All,

I did and ATAC-Seq experiment in different cell lines and I was curious to see if they have different motifs in the open chromatin. I was planning to use HOMER for this, but running from linux bash:

Code:

findMotifsGenome.pl ATAC_d001_peaks_called_with_homer.txt hg38 ATACAd001_FIND_MOTIF

I got this message of error (see below), it looks like the problem is in assignGeneWeights.pl line 63. Any tips on how to fix it?
        Position file = ATAC_d001_peaks_called_with_homer.txt
        Genome = hg38
        Output Directory = ATACAd001_FIND_MOTIF
        Fragment size set to 400
        Found mset for "human", will check against vertebrates motifs
        Peak/BED file conversion summary:
                BED/Header formatted lines: 0
                peakfile formatted lines: 42719

        Peak File Statistics:

                Redundant Peak IDs: 0
                Peaks lacking information: 0 (need at least 5 columns per peak)
                Peaks with misformatted coordinates: 0 (should be integer)
                Peaks with misformatted strand: 0 (should be either +/- or 0/1)

        Peak file looks good!

Hello.

I have the same. Have you solved this problem?
