Hi I found it in a 256x256x256 space while the T1 we use is in different space, I found this page on the registration step: http://surfer.nmr.mgh.harvard.edu/fswiki/FsAnat-to-NativeAnat I wish to know how this script work?
mri_label2vol --seg aseg.mgz --temp rawavg.mgz --o aseg-in-rawavg.mgz --regheader aseg.mgz
what is the transformation used ? JG

Hi Johnson - The aparc+aseg.mgz is in the same space as the T1 used as input to freesurfer.

Hi FS expert I need to know the transformation matrix itself since I will do the transformation in matlab. I successfully transformed white matter fibers coordinates to T1 using AIR 5.0 from LONI lab. They provide a transformation matrix. Now I want to transform the coordinates from T1 to Freesurfer space, so my question is: what is the transformation matrix that relates the T1 which FS have used for parcellation and segmentation with the aparc+aseg.mgz file? I searched the logs but couldn't find such matrix. I don't want to do a registration step since it will be less accurate than the one that was generated during the segmentation process. Also is it just one transformation or a combination of transformations?
thanks
