Storing minigraph index for multiple queries

[vikshiv]

Hi Heng,

I was running Minigraph to align a few assemblies to the HPRC v1 graph from PGGB. I plan to align a large number of regions from assemblies using minigraph -x asm hprc-v1.0-pggb.gfa <query.fa>. Is there a way to store/serialize the minimizer index of the graph, similar to how minimap can store the index for re-querying? Running just minigraph -x asm hprc-v1.0-pggb.gfa alone with no query builds the index, but it doesn't output or serialize anything.

Wanted to check if this was currently possible.
