I would like to use ADNI AV45 PET data for voxel wise study in MNI space. I downloaded the completely processed ac-pc, std, smoothed images but was wondering what transformation needed to be used to transform these images to the MNI 152 space. Are the preprocessed images already in a common space, so I can use the same linear transformation to get them to MNI linear space and then subject specific nonlinear transform to get to MNI non linear space?
These images have not been spatially warped. It is probably best to run whatever routine you normally use to get into MNI space on each set independently.
I do not know of what the typical transformation would be, although these are all oriented to Talairach atlas space (but without spatial warping).
