problem with co-FSEOF

[Laminsecin]

I get the following error when I am trying to run fseof:
Error using spdiags (line 95)
For the syntax spdiags(B,d,m,n), the size of B must be min(m,n)-by-length(d).

Error in fluxVariability (line 176)
QPproblem.F = spdiags(minNorm,0,nRxns,nRxns);

Error in testresultsFVATargets (line 22)
[minFlux,maxFlux] = fluxVariability(model,100,'max',ProductRxnsList);

Error in coFSEOFTargets (line 57)
Amp = testresultsFVATargets(model,minBM,solver,coFseofTargets{:,1},coFseofTargets{:,2},{'amp'}); %multiple
amps (A)

Error in FSEOF_1 (line 20)
TargetsScoreTable= coFSEOFTargets(model,minBM,solver,TargetProducts);

The fluxVariability function runs without any error for me. Can you let me know if the error occurs with any model (try ecoli_core model), or only with your model of interest?
If the latter is true can you give more information on the model you are using and the product of interest so that I can try it and get back to you? Also, mention the MATLAB version and solver version.
