Objective is none #1

Closed pbelmann closed 3 years ago

pbelmann commented 3 years ago

Hi Daniel,

I build multiple models using carveme and I wanted to use FBA in order to view flux distribution and escher maps. However viewing the solution it seems that the Objective is none and Status is unbounded. Does it mean that the model is wrongly build? Could you give any recommendations on how to proceed?

Did you define a growth medium ?

pbelmann commented 3 years ago

No

The model you are using probably doesn't come with a growth medium pre-defined, you need to define one yourself.
