Samtools format errors

[paulinarosales]

Hello,

I want to report a bug on HISAT3N output format, when trying to use the SAM output file for sorting or viewing with samtools the following errors appear:

[W::sam_parse1] empty query name
and
[bam_mating_core] ERROR: Couldn't read header

I checked the lines and the entries seem to have no tab spaces between fields:

❯ cat sample1.sam | head -n 109446607 | tail -n 1 | perl -pe 's/\t/ <tab> /g'
