Hi SPMers,

I have,

(i)  the coordinates of my EEG electrodes in MNI space

(ii) the y_*.nii and iy_*.nii files (deformation fields from SPM segmentation that is used to transform

     back and forth from subj->MNI.

Does anyone know how to use the deformation fields on the 3D coordinates in MNI space to get the

electrode locations in subject space?

Thank you.
