Default Error in htseq-count

Hi all,

I am having a problem when I try to run htseq-count. This is the sentence that I am using:

htseq-count -f bam -s no -i ID -t window mybam.bam > counts_file.count

This is the error:

77000 GFF lines processed.
Error occured when reading beginning of SAM/BAM file.
object of type 'NoneType' has no len()
[Exception type: TypeError, raised in _HTSeq.pyx:771]

And this is my bam header:

Thanks, all, for the pointers, but I'm still unclear as to how to apply the solution that's mentioned in the bug report (which is still tagged as "open").

I found the three instances of the string that needed correction (per the advice in the report), changed them and recompiled, but I still get the same error.

You might just give featureCounts a try. It should be faster anyway.
