External Email - Use Caution
Just to clarify: mris_fwhm or mri_glmfit is the last command I need to run? Can I extract SUVR values from all.lh.mgx.ctxgm.fsaverage.sm05.nii.gz?
Thank you

External Email - Use Caution Hello FS,
I have calculated regional SUVR and would like to calculate SUVR on the surface. I have followed the wiki tutorial, including PVC, through smoothing on the surface. The last commands I ran are:
mris_fwhm --smooth-only --i all.lh.mgx.ctxgm.fsaverage.sm00.nii.gz --fwhm 5 --o all.lh.mgx.ctxgm.fsaverage.sm05.nii.gz --cortex --s fsaverage --hemi lh mris_fwhm --smooth-only --i all.rh.mgx.ctxgm.fsaverage.sm00.nii.gz --fwhm 5 --o all.rh.mgx.ctxgm.fsaverage.sm05.nii.gz --cortex --s fsaverage --hemi rh
Do I need to run the mri_glmfit command? For example: mri_glmfit --y all.lh.mgx.ctxgm.fsaverage.sm05.nii.gz --surface fsaverage lh --fsgd g1v0.fsgd mri_glmfit --y all.lh.mgx.ctxgm.fsaverage.sm05.nii.gz --surface fsaverage rh --fsgd g1v0.fsgd
Will the mri_glmfit output provide surface-based SUVR, or will I need to run additional commands after?
Thank you, Mia
