General question about averaging

Hi,

Could someone refer me to any source or explain me how the averaging works
in MEG?
I understand that the location of the sources are unique for each subject,
and so sensor data can't be averaged. I wonder how it works with the source
data. Can they be averaged across subjects or is there an extra step as to
make each source data point in the same space coordinate for all subjects?

Thank you,
Ade

hi,

I invite you to read: https://www.ncbi.nlm.nih.gov/pubmed/24161808

in particular the paragraph on "Surface-based normalization"

you have a pdf here:
https://pdfs.semanticscholar.org/8d1b/879f26e176c7864ae4162947496d83a97ddb.pdf

or section 2.5 in
https://www.frontiersin.org/articles/10.3389/fnins.2013.00267/full

you can also look at:
https://www.biorxiv.org/content/early/2017/12/28/240044
that comes with code you can read.

HTH
