Hi there

I created labels on surfaces of subjects (chimp) registered to a particular volumetric template. The labels were created on the surfaces in Freeview using Freesurfer 7.1.

Since creating these labels, I improved the intensity inhomogeneity in the scans and re-ran the surfaces. When I try to use mri_label2label to transpose the labels to the new surfaces of each subject, the labels do not fall exactly where they should. In fact, the surfaces themselves have a slight translation in them (see snapshot). I assume this is because my registration to the template that I did prior to running recon-all is differing somehow between the 2 groups. However, I thought that this should not matter since mri_label2label --regmethod surface is using the sphere.reg to fsaverage.

I am wondering if there is anything I can do to improve mri_label2label to avoid editing the labels manually?

Thank you for your time,

Trisanna
