Subject: PetSurfer surface-based SUVR

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
