Dear Vladimir,
I have EEG data for which I have computed the head-modeling for source
reconstruction.
Now I would like to compute the source reconstruction on another
condition (another set of trials) of the same subject, but I would
like to avoid re-doing the head-modelling bit. How can I do? In your
reply below you say that it's possible to save it. What should I save
exactly and how can I reintegrate it in the new set of trials?
Thanks,
Marco
