AFNI Message Board

Dear AFNI users-

We are very pleased to announce that the new AFNI Message Board framework is up! Please join us at:

https://discuss.afni.nimh.nih.gov

Existing user accounts have been migrated, so returning users can login by requesting a password reset. New users can create accounts, as well, through a standard account creation process. Please note that these setup emails might initially go to spam folders (esp. for NIH users!), so please check those locations in the beginning.

The current Message Board discussion threads have been migrated to the new framework. The current Message Board will remain visible, but read-only, for a little while.

Sincerely, AFNI HQ

Hello,

Is there an advantage in SurfSmooth to passing multiple surfaces using the -surf_A, surf_B commands. In the afni_proc generated example, -surf_A is used to specify the smoothwm surface. I have seen some examples where both smoothwm and pial are passed with surf_A and surf_B, respectively. How does the program behave differently if two surfaces are given instead of one. I've pasted two sample calls below: 

SurfSmooth -spec /workingdir/Nifti/derivatives/sourcedata/freesurfer/fsaverage/SUMA/fsaverage_lh.spec \
        -surf_A smoothwm \
        -input $subj.r$run.hemi-${hem}.tcat.func.gii \
        -met HEAT_07 \
        -target_fwhm 9.0 \
        -blurmaster rm.errts.$subj.r$run.hemi-${hem}.func_REML.gii \
        -output $subj.r${run}.hemi-${hem}.blur.func.gii



SurfSmooth -spec /workingdir/Nifti/derivatives/sourcedata/freesurfer/fsaverage/SUMA/fsaverage_lh.spec \
        -surf_A smoothwm \
        -surf_B pial \
        -input $subj.r$run.hemi-${hem}.tcat.func.gii \
        -met HEAT_07 \
        -target_fwhm 9.0 \
        -blurmaster rm.errts.$subj.r$run.hemi-${hem}.func_REML.gii \
        -output $subj.r${run}.hemi-${hem}.blur.func.gii


Thanks in advance!
