How to import a custom model (iRP911) not listed in BiGG Models into COBRApy?

[chriscui0823]

I'm trying to analyze a metabolic model named ​iRP911 reported in the literature (Reference: [Genome-scale reconstruction and system level investigation of the metabolic network of Methylobacterium extorquens AM1]). However, this model is not available in the BiGG Models database.
Could you please guide me on how to properly import this model into COBRApy for flux balance analysis?

You have to locate a file of the model which can be read by cobrapy. Ideally, an SBML file.
This is provided in the reference:

The computer model of iRP911 written in Systems Biology Markup Language (sbml) is given in the additional file 16.

Unfortunately, the file is not valid and does contain a ton of issues. So you should contact the authors and ask for a valid file of the model which can be loaded.
