deeptools computeMatrix error

Hello,

I am facing some problem using deeptools (deeptools 2.4.2). Someone please help me solving this issue.

Command:

computeMatrix scale-regions -S ./H3K4me2_sorted_nodup.bigWig -R genes.bed --beforeRegionStartLength 2000  --skipZeros -o ./H3K4me2_sorted_nodup_matrix.mat.gz

Input (header):

track type=wiggle_0 name="H3K4me2" description="H3K4me2_sorted_nodup"
variableStep chrom=chr1
56375   3
56385   3
564493  3
564503  5
564513  5
564523  4
564533  4
564543  6

Error:

[bwHdrRead] There was an error while reading in the header!

That's a wiggle file, not a bigWig file. You'll need to convert it.

Yes, sorry. It is working perfectly. Thanks for the tool (saves lot of time).
