Dear experts,

I have suv data and I want to do pve using pet surfer. I have the following questions and would appreciate your help:

1. The output of mgx is three maps mgx.{ctxgm,subctxgm,gm} these maps are pvc corrected. I am wondering where can I find pvc corrected maps for whole brain (white matter and gray matter)?

2. can I register these mgx files to standard space and run voxel-wise comparison using FSL randomise?

3. The output of RBV method is rbv.nii.gz. I want to concatenate all the rbv files for two groups and run voxel-wise analysis comparison. Is this possible? The size of these files is pretty large! Do you recommend better way to study the difference between two groups using these RBV files?

4. Are these RBV files for white matter and gray matter?

5. The suv data is an output of single frame PET data with no arterial blood sampling. Do I still need to re-scale over the pons? 

Thanks in advance
