saving Comodulogram with BIC selection about pactools

[TomDLT]

Could you send the full traceback ?

Sorry, here it comes

Oh I see, this is when you are saving the comodulogram.
We cannot currently save a DAR object with h5io, not sure what is the best workaround.
Maybe we should just not save the DAR object in this case, what do you think?

[lepmik]

Saving the DAR object would be a good idea, or extract all parameters that is necessary in order to replicate the analysis.
