addMultipleReactions error in mgPipe tutorial about cobra.tutorials

Hi Matt,
may you try also updating the COBRA.papers folder to test if that solves the issue?

Hi all,

I think I found a bug in mgPipe tutorial(tutorial_mgPipe.m).

In line 205

[init, netSecretionFluxes, netUptakeFluxes, Y, modelStats, summary] = initMgPipe(modPath, abunFilePath, computeProfiles, 'dietFilePath', dietFilePath, 'infoFilePath', infoFilePath, 'saveConstrModels', saveConstrModels, 'numWorkers', numWorkers);

should be

[init, netSecretionFluxes, netUptakeFluxes, Y, modelStats, summary] = initMgPipe(modPath, abunFilePath, computeProfiles, 'dietFilePath', dietFilePath, 'infoFilePath', infoFilePath, 'numWorkers', numWorkers);

It seems that initMgPipe() module does not support 'saveConstrModels' option anymore.

And I encountered another error in the initMgPipe module like follows

Error using microbiotaModelSimulator>(parfor supply)
An UndefinedFunction error was thrown on the workers for 'Diets'.  This might be because the file
containing 'Diets' is not accessible on the workers.  Use addAttachedFiles(pool, files) to specify
the required files to be attached.  For more information see the documentation for
'parallel.Pool/addAttachedFiles'.

Error in microbiotaModelSimulator (line 179)
        parfor k=s:s+endPnt

Error in tutorial_mgPipe.m (line 205)

Caused by:
    Undefined function or variable 'Diets'.

Could you advise me to solve this problem?

Best regards,

Hi Young-Ho, the input parameter has indeed been removed and models with diet constraints are now always saved. This has already been changed in the tutorial on the develop branch, but not yet in the master branch. Unfortunately, I cannot reproduce the second error. Kind regards, Almut
