[Mne_analysis] MNE source estimate analysis with multiple conditions

[Lyam Bailey]

I suppose we could equalise the number of epochs per condition, in theory (although I'm not familiar with the best way to do this). Basically the unequal epoch numbers arose due to problems during data collection, whereby a few random trials were lost in almost every subject.

Does your experimental logic allow you to equalize the number of epochs per conditions or do you have some rare events by design?

Hi Alex,


Thanks for the tip! I'm glad you mentioned this because as it happens, I don't have the same number of epochs for each condition. Can you suggest a work around?

tiny detail: this will only be true if the two conditions have the
same number of epochs averaged in each condition.
