I am trying to generate spatial patterns in simulated data by
manipulation of forward solution file. Although I can read the forward
solution file and overlay pattern over its data, I cannot seem to figure
out a way to write a new forward file in matlab which I can use with
mne_simu command afterwards. Is there a function I can use for this?
I do not believe this is supported. If you are importing the forward
solution why not simulate the data when you have imported it i.e.
directly in matlab. The other option is to save label files of the
sources you are interested in.
