Hi, doug Thanks so much for your answer. Acctually I use the volume-based registration in order to get the talairach coordinate for each vertex in the label. 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 talairach space, considering the label is from a surface? Best! Jin

You used the volume registration method and that won't work for surfaces. If the original label is from a surface, then use the surface-based registration method.

Hello there, I tried mri_label2label to convert label in a subject's space into label into fsaverage's space. I used the command mri_label2label –srclabel C102/label/lh.pfc.C102.label –srcsubject C102 –trglabel fsaverage /label/lh.pfc.fsaverage.label –trgsubject fsaverage –regmethod volume
The generated label was supposed to be in the same space with fsaverage, but when loaded on fsaverage's inflated surface, only scattered lines was seen. While when loaded on subjects's surface, it looks normally, but the image was exactly the same as the original label (see attached image). I tried this again and the problem exist, I also compared the command with that online, and haven't found the cause to this problem. What's wrong with my command? By the way, if I want to convert the label in a subject's space into talairach space, could the above command achieve this? The freesurfer I used was freesurfer-linux-centos4-stable-pub-v5.0.0 Any help would be greatly appreciated.
Thank you in advance.
Best, Jin
