fastFVA error

[AgustinPardo]

Hello, I am trying to run "fastFVA" function of cobraToolBox using Matlab R2018b on Linux 18.

This is the model I am using: http://bigg.ucsd.edu/models/iEK1008.

I run this:

[v11, v12] = fastFVA(iEK1008)

I get this:

 > The exact version of CPLEX could not be determined
Error using fastFVA>checkFastFVAbin (line 746)
Official binaries are only available for CPLEX version 128. You have installed version . Please run: >> generateMexFastFVA() in
order to generate a new binary file.

Error in fastFVA (line 130)
checkFastFVAbin(cplexVersion);

Error in run_prom (line 41)
[v11, v12] = fastFVA(iEK1008);

Do you know what is happening and how to solve it?

Regards

I hereby confirm that I have:

• [x] Tried to solve the issue on my own
• [x] Retried to run my code with the latest version of The COBRA Toolbox
• [x] Checked that a similar issue has not already been opened

(Note: You may replace [ ] with [X] to check the box)

Hi @AgustinPardo Do you have IBM cplex installed?

Hi.

I also had a similar error when running AGREDA 1.0 using CPLEX 12.8 and Matlab 2018b on Ubuntu 20.04/Windows

I think this is due to a bug in fastFVA.m. In my opinition, because throwBinGenerationError will be false when an appropriate binary version of CPLEX is found in the above code, "if throwBinGenerationError" on line 758 of fastFVA.m should be "if ~throwBinGenerationError".

Hi Young-Ho, Ines Thiele has implemented a bugfix for fastFVA.m https://github.com/opencobra/cobratoolbox/tree/master/src/analysis/FVA/fastFVA/mex and generated a new binary for Windows. Subsequently, also Tim Hensen generated an additional new binary https://github.com/opencobra/COBRA.binary/tree/master/win64/bin/fastFVA Unfortunately, the new binary for Cplex 12.8 on Windows has not yet been generated, but if you follow Ines' guide https://github.com/opencobra/cobratoolbox/blob/master/src/analysis/FVA/fastFVA/mex/README.txt you could do a bit for the community by generating them and making a PR to COBRA.binary. Use testFastFVA to check it works correctly. Regards, Ronan
