Hi,
I'm trying to follow the tutorial for HLA typing and assembly in HISAT2 as described at http://ccb.jhu.edu/hisat-genotype/index.php/Type:HLA using my own RNAseq data. I do everything as described. I have samtools 1.7 installed. I am able to extract my HLA reads. But when I get to the last step, the typing and assembly, I get an error "no such file or directory". There seems to be a bam file missing. There is a newly created one in my directory called "-o.bam" but none with the specific name requested.

Any help would be greatly appreciated. Thanks.

with high verbose level and many similar lines deleted for brevity:
