Hello there,
First and foremost, I must note that I am a beginner at SPM (I've done the basic tutorials). So please, be as detailed as possible with any answers. We are using subjects from the ADNI database and each subject has both a vMRI and PET scan. I am hoping to coregister the PET and MRI to one another. Based on recommendations from ADNI, the images that I downloaded from the database have undergone the following pre-processing steps (prior to SPM import):
PET: Coreg, Avg, Std Img and Vox Siz, Uniform Resolution
MRI: MPR GradWarp B1 Correction N3 Scaled
What would you recommend that I do to successfully coregister these images? Should I take an re-alignment steps at all?
Monika
