How to extract C-flux values from model.summary() function

[Yahya Farooqi]

Hello everyone, 

I have noticed that when running the model.summary() function, and subsequently running .to_frame function, that the convenient "C-flux" metric seems to disappear. 

When running the .to_html and .to_string functions on the same object this problem does not exist. 

I have written a function that can extract these values from the html, however it would be nice to have these values stored in a consistent dataframe. Does anyone know how to do this? Perhaps there is something I am missing. 

What I am doing now:

summary = model.summary()

summary_frame = summary.to_frame()
