IGV not finding sequence from bam file generated from a graphmap2 sam file

[Coahuila]

Hi,
I have Oxford Nanopore DNA sequences (from Plasmidsaurus) that I'm generating sam files through graphmap2, and ultimately making sorted bam files. However, the bam files show no sequence when I load them into IGV. The reference fasta is only 700bp long. My guess you could look at an output sam file and tell me the issue, but I can send you whatever files would help. I would appreciate any kind of direction you might give.

Thanks,

Patrick
