Hi Guang,

don't confuse the geometric atlas (*.tif) that is the target of registration with the classification label atlas (*.gcs) that is used to generate the parcellations. You probably don't need to regenerate the registrations if you are simply creating a different classification atlas, so the sphere.reg should be fine

cheers, Bruce

  Hi, there,

I have created our own template and am creating our own atlas now. I have annotation files for each subject in my training set, and my mris_ca_train command line is:

mris_ca_train -n 2 -t /home/freesurfer-install/freesurfer/ATLASColorLUT.txt lh sphere.reg myatalas.annot custom_1 custom_2 custom_3 custom_4 lh_myatlas.gcs

my question is here, I should use the lh.sphere.reg file which register the sphere to the FS default template or the registration file which register the sphere to my own template?

Thanks! Guang
