Thank you so much for your answer.
If I understand correctly there is a problem with mixed models and it is that you don't have parcellation of the cortex so you either have cortex and all subcortical or cortex detailled with another model but without the subcortical. That's what I mean I believe I need to use Volume models.
I have done MNI atlases AAL and I want to obtain functinal connectome. I have seen this debate in the forum before although I am trying with MEG data from tutorials I aim to do with EEG epilepsy data. AAL3 scouts with MEG.
I have seen this article doi:10.1093/brain/awp028. But they have done this in SPECT not EEG or MEG showing the utility of cerebellar activity in epilepsy. So I am wondering what should I do if it is possible to do with brainstorm in EEG. I have seen this article https://doi.org/10.1016/j.neuroimage.2020.116817. So I just need to know details regarding of brainstorm.
Thank you for all the help in advance.
