Hello,

I am using Minimap2 for the Oxford nanopore reads. I made an index file for the human genome to be used as a reference. when I started the alignment I got following warning.

"For a multi-part index, no @SQ lines will be outputted"

I am not sure why I am getting this warning. Could someone help me here?

Thank you in advance.

The command I used for building index:

minimap2 -d ref.mmi ref.fa

The command I used for alignment:

minimap2 -ax map-ont ref.fa ont-reads.fa > aln.sam

I have got help from the authors of minimap2. I downloaded the reference from here which is very confusing. when Replaced the reference with this Minimap2 works fine.
