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

That is all you need to run!

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
