I think that will work, but there are better tools for this kind of thing. If you have 7.4, you can use mri_binarize, like mri_binarize -dilate-vertex vno surf radius outmask where vno is the center vertex, surf is the surface (eg, white), radius is the desired radius of the cicrle, and outmask

We usually use the white surface because its placement is independent of the placement of the pial surface (and so independent of thickness and volume), but it is really an empirical question. On 12/12/2023 11:26 PM, free_learner wrote: External Email - Use Caution Dear experts, Sur

You are right that using all the scans will bias toward tp2. I think I would just run the cross for each time point using all the data you have. This will not bias the base because an average of the images within each time point will be used to make the base. If possible, you will want to make
