[Mne_analysis] MNE processing (to get *stc file)

[Hendrik Santosa]

Hi Eric, 
Thanks for your response. Could you please give me the detail information about 'plot-alignment'? How to use that function, etc. Also, where I can find the argument for "vector' modes in 'apply_inverse'.
Thanks!

Overall, I have got the results which are not what I expected (the frequency and spatial response are different with the channel space).

With a loose (or free) orientation inverse, calling `apply_inverse_*` without the default pick_ori=None argument will end up taking the absolute value. This nonlinearity can change the frequency response, which would otherwise be preserved by a linear transformation (which you would have with the pick_ori="normal" and "vector" modes)..
As for the spatial distribution being different, you might want to use `plot_alignment` to verify your sources, conductor model, and sensors are properly aligned.
Eric
