GEMtractor

The GEMtractor is a platform for trimming and extracting genome-scale metabolic models (GEMs).

Using the GEMtractor you can trim (currency-)metabolites, reactions, genes, or enzyme complexes off you GEMs, to for example focus on subnetworks as reported by prior flux balance analyses.
From the trimmed model you may then extract the Reaction-centric or Enzyme-centric network, wich can be exported in different graph formats for subsequent analyses.

The GEMtractor comes with support for Docker — installing an own instance is pretty easy, see Run your own GEMtractor.
It also features an API, so you may use the GEMtractor from your software tools.
There is plenty of more information at the FAQ and the Python documentation.

If you dare to harvest your models, check it out at GEMtractor.bio.informatik.uni-rostock.de!
