Hi Freesurfer experts,
I am trying to resample the cerebellum atlas Buckner2011_17Networks_MNI152_FreeSurferConformed1mm_LooseMask.nii.gz to fmriprep output volume ${sub}_task-rest_bold_space-MNI152NLin2009cAsym_brainmask.nii.gz. I was wondering if the following 3 procedures are equivalent (if not what’s the difference?)?
1. mri_vol2vol --mov ${FREESURFER_HOME}/average/Buckner_JNeurophysiol11_MNI152/Buckner2011_17Networks_MNI152_FreeSurferConformed1mm_LooseMask.nii.gz --s ${sub} --targ ${project_path}/fmriprep/${sub}/func/${sub}_task-rest_bold_space-MNI152NLin2009cAsym_brainmask.nii.gz --o ${output_file_path}/Buckner2011_17Networks_MNI152NLin2009cAsym_brainmask.nii.gz --nearest
2. mri_vol2vol --mov ${project_path}/fmriprep/${sub}/func/${sub}_task-rest_bold_space-MNI152NLin2009cAsym_brainmask.nii.gz --s ${sub} --targ ${FREESURFER_HOME}/average/Buckner_JNeurophysiol11_MNI152/Buckner2011_17Networks_MNI152_FreeSurferConformed1mm_LooseMask.nii.gz --o ${output_file_path}/Buckner2011_17Networks_MNI152NLin2009cAsym_brainmask.nii.gz --nearest --inv
3. mri_vol2vol --mov ${FREESURFER_HOME}/average/Buckner_JNeurophysiol11_MNI152/Buckner2011_17Networks_MNI152_FreeSurferConformed1mm_LooseMask.nii.gz --s ${sub} --reg register.dat --o ${output_file_path}/Buckner2011_17Networks_MNI152NLin2009cAsym_brainmask.nii.gz --nearest where register.dat was generated by the following: bbregister --s ${sub} --mov ${FREESURFER_HOME}/average/Buckner_JNeurophysiol11_MNI152/Buckner2011_17Networks_MNI152_FreeSurferConformed1mm_LooseMask.nii.gz --int ${project_path}/fmriprep/${sub}/func/${sub}_task-rest_bold_space-MNI152NLin2009cAsym_brainmask.nii.gz --init-coreg --reg register.dat --t2
Thank you for your time!
