Hi everybody!
I have have a problem reguarding MNI coordinates.
I receive from the program LORETA (a program to see the results of EEG
experiments) the coordinates of a point in mm (mni) (the axis in LORETA are
in 'mm mni') and I have to obtain the coordinates in voxels of that point. In
order to do this, I thought to open an image from the SPM templates (I use
SPM5, with the function 'display'), because I know they are all in MNI space,
write the coordinates I have in millimeters, and watch the corrisponding
coordintes in voxels. Anyway I noticed that those images havn't always the
same origin (for exemple EPI, or T2, have different origins). Then I thought
maybe I should use the images in the folder "EEG canonical", but they also
have different origins one from each other. Which image of the templates
should I use, in order to have an MRI image in MNI space with the same origin
of the point I get from LORETA?
Thank you very much for your help!
