I'm trying to source localize my MEG data (preprocessed data), but couldn't
find out where I'm going wrong.
I'm attaching code with this mail.
Any suggestions or comments are welcome.
Thank You

Hi Vivek,
Check your noise covariance matrices. Generally you should use empty room
data or baseline i.e., pre-stimulus activity. You should not use
post-stimulus data unless you are using beamformers to compute source time
course.

Dear Dip,
My MEG data is a resting state data. It does not have any stimulus.

Hi!,
I don't have much experience with resting state data but I am not sure if
you can use a noise covariance matrices created from the raw data for
distributed source methods (e.g., dSPM or MNE) . Don't you have empty room
data?

No.
