Dear freesurfer team,
I am dealing with PET scans that were acquired at different sites. They do not have uniform voxel size and dimensions. I was wondering if this would be an issue for the sGTM and MG PETSurfer-PVC and/or for the "vol2surf --projfrac 0.5" and vertex-wise PET group-analyses. Should I resample to a uniform voxelsize prior to these steps or does freesurfer take care of this issue internally?
Thank you for the information. Best regards Julie
