Hi,
I have a question about spherical registration, and I couldn't find a relevant answer in the mailing list.
I have two subjects S1 and S2 with corresponding functionals. I want to show the functionals of each subject on the surfaces of the third subject S3. I have .sphere files for S1, S2, and S3, but I don't have .sphere.reg files yet because these are monkey subjects and I did not want to register them to the buckner40.tif template. Since my goal is not group averaging, and it is just to map functionals to the same-subject anatomicals and then to the target-subject anatomicals, I was thinking of one of the following solutions:
1) Convert sphere of S3 to a template .tif file, then use mris_register to register spheres of S1, S2, and S3 to that template and generate sphere.reg for all the subjects. Not sure if mris_make_template works for one subject though.
2) Make a template from "S1 and S2" through the procedure described at https://surfer.nmr.mgh.harvard.edu/fswiki/SurfaceRegAndTemplates#Creatingare.... Then register S1, S2, and S3 to that template and generate sphere.reg for all the subjects.
Which approach is recommended?
BTW, I do not know of a monkey template that is based on the surfaces from a large group of monkeys.
Thanks for any advice, Reza
