[FieldTrip] extracting virtual time series in MNI space

[Arjen Stolk]

Hey Vasan,

One way to do that is by 'normalizing' the subject's grid such that its
points relate to specific points in MNI space. The procedure is described
here:
http://www.fieldtriptoolbox.org/tutorial/sourcemodel

Using ft_volumelookup you can subsequently find the subject's grid points
(now in MNI space) belonging to ROIs.

Hope that helps,
Arjen
