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_templatehttps://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.
Thanks, David

Hi David
usually you need a ?h.sphere.reg as the ?h.sphere files are in (arbitrary) spherical coordinates, while the ?h.sphere.reg ones are in registered ones

Hi everyone,
If I only have lh.sphere and lh.sulc files for each of collection of subjects, would this be enough information to generate a template for registering further subjects?
I was thinking of trying to follow the workflow described on the page:
https://surfer.nmr.mgh.**harvard.edu/fswiki/**SurfaceRegAndTemplateshttps://surfer.nmr.mgh.harvard.edu/fswiki/SurfaceRegAndTemplates
(in the section titled "Creating a registration template from scratch (GW)"), but wasn't sure whether more than just native spherical coordinates and convexity information would be implicitly required by the mris_make_template command. (The "Positional Arguments" table that appears on the page:
https://surfer.nmr.mgh.**harvard.edu/fswiki/mris_make_**template<https://surfer.nmr.mgh.harvard.edu/fswiki/mris_make_template>only asks explicitly for references to the hemisphere data for a collection of subjects.)
Thanks in advance for you help, David Romano
(P.S. There's also appers to be a typo in the "Positional Arguments" table I mentioned above: In the description section for position 2, the {hemi} and {sphere_name} values seem to be reversed.)
