Hi, I am a new user of MICOM.
I was going through the training in the documentation and encountered a problem in the chapter 'Elasticities'.
The output is very different from the sample.
Why?

The table below shows the output of elasticities() in my environment.

reaction taxon effector direction elasticity type

1 EX_acald_m medium EX_akg_m forward 0.0 exchanges

3 EX_co2_m medium EX_akg_m forward 0.0 exchanges

Yeah this is because the elasticities are very dependent on the initial solution and the one in the docs were generated with CPLEX and not with OSQP (which gives the results you have seen). I'm planning on rewriting the elasticities part soon, so hopefully that will fix this.
