Hello Feliks,

I would just add that the read name reported in your picard error:

> Exception in thread "main" net.sf.picard.PicardException: Illegal
> mate state: HWI-ST1006:65:C0VRNACXX:2:1102:15430:43570

looks like the standard Illumina naming scheme, and, to my limited
understanding, you should not be finding collisions in read names unless
there is a configuration problem upstream. The same caution is noted on
the github page you link:

"Note that such improperly named reads might indicate a failure in an
early stage of the sequencing pipeline"

For troubleshooting purposes, it might be useful to grep the BAM/SAM
file for the read name in the error and see (a) how many lines are
returned, and (b) what the flags tell you about the alignments
returned and how many read pairs they represent. Also, regarding your
issues with the 'resolvepair' script, the description notes "resolvepair
requires SAM input sorted by read name", which I suspect the tophat
output is not, so you might try this sort if you haven't done so
already.

Regards,
Jeremy
