How to use the C matrix with Julia

[jialin3299]

Hello, when I used the new version of COBRA Toolbox to generate the personalized community model, the C matrix replaced the original A matrix. When I tried to calculate the metabolic flux of C matrix with Julia, the code reported an error, which showed that there was no C matrix in the model. I wonder if the error was caused by the change of the internal structure of the model. Can Julia calculate C matrix now?

ERROR: LoadError: Matrix 'C' dose not exist in 'microbiota_model'.
