Hi, Freesurfers, As the *.label file provide the vertex number and R,A,S positions. How could I get the corresponding position in Talairach coordinates for each vertex? That is, how could I convert the label in a subject's space into that in talairach space, considering the label is generated from a surface, like shown in the attachment? I tried to use mri_label2label to convert the label into fsaverage space, but when shown in tksurfer, the RAS position was not similar to Talairach position in fsaverage. Any help would be appreciated. Best! Jin
