That's in contrast to >95% properly paired in the submitted bam file, so the problem seems to be in processing, not the original submission.

For single end data, each read is treated as a fragment and therefore the value of this parameter should be set to TRUE. properlyPaired: logical indicating if only properly paired reads will be ... WebPaired-end reads are always discarded pairwise (see also --pair-filter ). The default is to not apply any filters. -m LEN [:LEN2], --minimum-length LEN [:LEN2] Discard reads shorter than LEN. If LEN2 is given for paired-end data, it is applied to R2. -M LEN [:LEN2], --maximum-length LEN [:LEN2] Discard reads longer than LEN. buy used firearms online
