[FieldTrip] Source Reconstruction: MNI or subject space

[Pelt, S. van (Stan)]

Dear Rajat,

Both options are fine in principle. The only thing to keep in mind is that you used a non-warped volume (with either a CTF or MNI-grid) when computing the leadfields. It is crucial that these are computed based on the actual physical proportions/relations of the brain and sensors.

Best,
Stan

Dear Rajat,

one option that is widely used by FieldTrip users, I believe, is the computation of source model aligned in MNI space while retaining the individual head model. This FAQ explains how to do this.

Dear FieldTrippers,

When you have to perform source reconstruction, do you do it in MNI space (after warping the T1 image to MNI coordinates?) or is it better to do it in the individual subject space?


Thank you.
