I'm having an issue with the "SAM-BAM conversion and sorting steps together" command. After the following command...

bwa mem -t2 -R '@RG\tID:NA12878\tSM:NA12878\tLB:NA12878' genome.fa SRR1611183_1.fastq.gz `SRR1611183_2.fastq.gz |samtools view -u -samtools sort -@2 - > SRR1611183.bam`

...I get the following error:

E::hts_open_format] Failed to open file sort

The command actually still runs but changes your SRR1611183.bam so that there is now 0 bytes on data in the file.

I'm a little scared to repeat this command since you need to reconstruct your SRR1611183.bam file which takes about 30-40 mins. I'd hate to wipe it out again.

Does anyone see a glaring error in my bwa mem script?
