Metabolite identifier mapping methodology

[Ronan MT Fleming]

Hi all,

I am trying to find a description of the methods used by BridgeDb to cross map metabolite identifiers between databases. I could not find it in the tutorial...

https://bioconductor.org/packages/devel/bioc/vignettes/BridgeDbR/inst/doc/tutorial.html

Or in the documentation ...

https://bridgedb.github.io/pages/docs.html

Please could someone point me to such a description?

What is the gold standard used to check that any metabolite mapping between databases is correct? e.g. are pairs of standard InChI's for neutral molecules compared?

Regards,

Ronan
