[Freesurfer] Questions about the transformation of DKatlas from surface to volume

2017-10-15 Thread Zhiqiang Sha
Hi, I have three questions about the transformation. (1) Is Desikan-Killiany Atlas in Talairach space? The volume was transposed onto the "inflated" cortical surface based on the image in freesurfer/average/mni305.cor.mgz ? (2) DK_atlas seems to be obtained from the inflation of interface of

Hi Zhiqiang (1) No, the manual parcellations were done in individual subject space, then compiled into an atlas in fsaverage/spherical warp coords. (2) We inflate the white surface, but I don't think inflating the pial would be much different. YOu can do it yourself if you want with

Thanks for your quick reply. For the third question, if I use talairach.xfm to transform the atlas in volume, it will go to the MNI305 space. However, how to transform the atlas from the Talariach to MNI152 space? And I will the atlas in volume format in other software related to the functional
