optimization status -2

[emilpaulitz]

Thank you for developing this tool! I wanted to use this tool to make condition-specific plant models. However, when running [reconstruction, reconInd, LP] = swiftcore(model, t.Var1, ones(length(model.rxns), 1), 1e-3, true);, I get:

Warning: Optimization was stopped with status -2
 
> In core (line 76)
In swiftcore (line 113) 
Output argument "flux" (and possibly others) not assigned a value in the execution with "core" function.

Error in swiftcore (line 113)
    flux = core(model, blocked, weights, solver);
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Now, I guess the error results from the problem not being feasible. Before diving into the code of what the problematic LP is and does, do you have any suggestions what could cause this error and what to check in my model?

Thank you in advance!
