Hi Bruce, The workflow that I mentioned from the wiki is for creating a new template in the absence of any ?.sphere.reg files; here's relevant language from the webpage:
---------------- "Creating a registration template from scratch (GW) (This section reports on what I (GW) have learned of the registration process from Bruce Fischl. and Doug Greve, along with reading the source code. I have not actually tried it.) The process of creating a template involves calculating a "mean" (across subjects) pattern of curvature-related values, along with the variance of these variables. This task is performed by program mris_make_template<https://surfer.nmr.mgh.harvard.edu/fswiki/mris_make_template>. However, mris_make_template expects the input subjects to be already aligned (ie: already have ?h.sphere.reg files). This of course will not be the case if you are about to create a template!" ---------------- This is context for my question.
