[FieldTrip] Source reconstruction using DICS : poor results

[CHATEAUX Manon]

Dear Jan-Mathijs,

Thank you for your quick and extremely helpful answer!

I indeed had been careful for my functionnal and anatomical data to be  
expressed in the same coordinate system as my recorded MEG data (4d).  
However, I had forgotten about the units : the source was in cm while  
the MRI was in m.

I tried what you suggested, adding a regularization parameter and  
computing the CSD using multitaping and it solved my problem.

Thank you again for your time,

Manon
