Overview The skill constructs or loads genome-scale metabolic models (GSMMs) in the COBRApy framework. It is the entry point for every metabolic flux analysis pipeline. Output is a validated COBRApy object serialized to a JSON file ready for downstream FBA and flux analysis. GSMMs encode every known metabolic reaction in an organism as a stoichiometric matrix. Constraints (reaction bounds, medium composition, objective function) turn the model into a solvable linear program. --- Workflow Step 1 — Decide: Load Existing or Build from Scratch Option A: Load a curated BIGG model Key BIGG model ID…
