Customize/update the Metacyc pathways database in PICRUSt2 for fungi

Hello,

I only use the pathway_pipeline.py component of Picrust2 because I’m working with fungi and the phylogenetic placement isn’t reliable for ITS.

Therefore, I would like up-to-date Metatcyc pathway_mapfiles for Fungi, including as many pathways as possible. Could you please tell me how you build these files so that I can recreate my own?
