Dear Aurelien, Attila,

Excellent bioinfo tool, congratulations!

I have two questions concerning to the metabolite annotation in the PKN

1/ Looking the full PKN network, I have realized that metabolites IDs with different nomenclature than HMDB have been also included, for example see below:
-Metab__HMDB0000132_c (HMDB nomenclature)
-Metab__4782_c (PUBCHEM nomenclature)
-Metab__c226coa_c (KEGG nomenclature)
-Metab__pa_hs_c (Unknown nomenclature)

I am wondering if the different metabolites nomenclature are taking into account when the function "format_COSMOS_res" is applied to rename metabolites or only HMDB?

2/ it is possible to add manually new nodes/interactions in the PKN while keeping the same format, right?

Many thanks for your help
Best regards,
