what are those three? The same data just oriented in a differeent way? If so, then it does not matter as long as the orientation info is correct. Load one into freeview to assure that the cor view actually shows up as cor, etc. One thing you will not be able to check is whether there is a left-right flip

        External Email - Use Caution        

Hi FreeSurfer Users,

I would like to perform PET analysis using PETSurfer and I have the following FDG-PET NIfTI files below:

1. TRANSAXIAL_BRAIN_3D_FDG_IR_CTAC+Time-TMGX.nii

2. SAGITTAL_BRAIN_3D_FDG_IR_CTAC+Time-TMGX.nii

3. CORONAL_BRAIN_3D_FDG_IR_CTAC+Time-TMGX.nii

Which of the 3 NIfTI files above should one use for the PETSurfer? 

Thank you.
