Conversion to MetanetX namespace

[zoey-rw]

I'm interested in converting this model to the MetanetX namespace, to make multi-species modeling a bit easier. With the current SBML file, the MNX importer wants to merge 4 reactions, including two NGAM reactions (r_4046 and r_4046_sce), which I figure were distinct for a reason:

Also, MetanetX won't map any metabolites by their IDs (even though over 40 metabolites have MetanetX identifiers in the annotations). So I started mapping metabolite IDs to MNX using their CHEBI/KEGG annotations, but this seems to increase the number of reactions that the MNX importer finds problematic or wants to drop entirely (possibly because of how I was trying to preserve any m_ or s_ prefixes, but didn't match MNX IDs for both the s_ or m_? Not sure.)
Since Yeastnet v8_3_4 is in the MNX repository, I wanted to reach out in case the importer problems may have already been identified or solved.

Alternatively, to avoid the MNX importer merging reactions, I would appreciate any advice for changing metabolite IDs to their MNX annotations! Thanks!
