[Mne_analysis] MNE in Matlab

[Adela Glez.]

Thank you. I still got the error that the number of arguments was wrong. It
seem to run adding just '1' for the argument "dSPM"). However, I get the
following error:

Error using fiff_read_evoked (line 83)

Could not find processed data



Error in mne_ex_compute_inverse (line 53)

data = fiff_read_evoked(fname_data,setno);


I noticed I have no -ave.fif file in the set of files computed with MNE
python.

Maybe that is the source of the issue?
