MACS2 IndexError: list index out of range

[Jondeen]

I get the following error stack upon running callpeak on my two BAM-files (through Galaxy). Any way I can troubleshoot what is wrong here?

~$ (macs2 callpeak --verbose 9 --name "MACS2" -t "/home/ogaard/gits/galaxy2/database/files/000/dataset_140.dat" -c "/home/ogaard/gits/galaxy2/database/files/000/dataset_116.dat" --format='BED' --gsize "11000000" --bw='400' --ratio 1.0 --slocal 1000 --llocal 10000 --broad --broad-cutoff='0.1' --keep-dup "1" --bdg --qvalue "0.05" )

Similar error. Could it be a BED formatted output problem?

format = BED

...

effective genome size = 4.90e+08

band width = 250

model fold = [5, 50]

qvalue cutoff = 5.00e-02

Larger dataset will be scaled towards smaller dataset.

Range for calculating regional lambda is: 1000 bps and 10000 bps

Broad region calling is off

Possible. The BED file input must contain at least 6 columns including chromosome, start, end, name, score, and strand, and the delimiter should be 'tab' or '\t'. 'White spaces' don't work. Perhaps you have to use galaxy tool to first convert the delimiter.
