I think they will give very similar results, but my guess is that #1 is a little better

I want to use the annotation file created by myself in fsaverage to calculate the anatomical stats, but i dont know what is the best workflow. 

1. Convert the annotation file to each subject space using mri_sur2surf and using mri_anatomical_stats in each subject

2. Convert the surface of each subject to fsaverage space and use mri_segstats to obtain the data, in this case i dont know what surface i have to convert to fsaverage space to do it (i can see thickness (lh/rh.thickness) and volume (lh/rh.volume) but not folding index and white matter volume)

Any idea?

Hi Alberto

 

1. And 4. Are not properties of single surfaces – they are computed from the white and the pial. For 2 and 3 that is really up to you

Cheers

Subject: [Freesurfer] Problem with freesurfer measures

 

        External Email - Use Caution        

Hello Freesurfer team, I am using an annotation file that i've created previously to obtain the measures of some ROIs. To do that i am using de commands mri_surf2surf and mri_segstats. I want to obtain the following measures:

1. Gray and White Matter Volume

2. Folding Index

3. Curvature measures

4. Thickness

However I don't know what surface in the surf folder of each subject I have to use. Could u help me?
