Problem with testFBA

  • Raphael

    Hi, I am installing the CobraToolbox 2.2 and I am having some problems, mainly with FBA and SBML.
    When I apply 'testall' I only get 3 modules working:


    I understand that I don't need all the modules working fine. However, I am about to do some FBA and, thus, this module must be working fine. I installed the glpk solver and tested it using glpktest1 and 2. Everything is working fine.
    When I do testFBA however I get the following error:

    ??? Attempt to reference field of non-structure array.

    Error in ==> optimizeCbModel at 161
    if (solution.stat ~= 1) % check if initial solution was successful.

    Error in ==> testFBA at 31
    solution = optimizeCbModel(model);

    Looking into the function optimizeCbModel I figured out that there is no variable called 'solution.stat'. There are actually variables called 'solutionStd.stat', 'solution2Std.stat', 'solution3Std.stat' and 'solution4Std.stat'.

    If anyone can help me with that would be great!

    Thank you!

    Did you ever figure this out?  I am running into the same errors except I get testSBML working as well.  I have it running on Mac OS X 10.7 and Matlab 2011b.  I did install the gurobi_mex files for the LP solver since the one included in cobra does not work for Mac OS 10.7.
