Dear All,
I need to export a T1.mgz and N points (Nx3 coordinates .mat file) of the same volume in SPM12b. N are actually intracranial electrodes. For this, I save T1.mgz as .nii prior to import into SPM. Should I use volume index, volume RAS or surface RAS coordinates for N? What other transforms I should apply to the .mat coordinate file so that when read in SPM is in the same space as T1.nii? Please advise, Thank you,
Octavian.
