Dear SPM experts:
I've downloaded about 700 preprocessed FDG-PET images from ADNI (http://adni.loni.usc.edu/). (The first 3 preprocess procedure has been done as listed in http://adni.loni.usc.edu/methods/pet-analysis/pre-processing/).
1. These preprocessed images has the dimension 160x160x96. (named as I001.img to I700.img)
2. We have interested in finding name of each subregion with respect to standard atlas (e.g. AAL, http://www.gin.cnrs.fr/spip-php-article217). For AAL, downloaded from the website, has the dimension 91x109x91.
Apparently, to match voxels in 1. and 2., I need to transform both of them into the same coordinate system. Is there any way to do this ?
