In the meanwhile i did some research, and it looks like freesurfer does not use MNI152 as default template, am i right? it seems that the default template is the fsaverage subject, which in fact does not look like very realistic.
Is there any way to get a realistic brain & segmentation that is "idealized" enough, and still in talairach space (freesurfer space)? maybe the MNI152 after recon-all and mri_transform to apply back the transformation? i am sorry if these questions look unreasonable, i am new of freesurfer, and still have problem orienting myself in the documentation :) best, Paolo On 05-Nov-11 00:57, Paolo wrote: > Hello > > I am a new user of freesurfer. > I was wondering whether the brain regions for the MNI152 dataset are > available anywhere (i mean the template brain regions for the default > MNI152 template). > > > I have also another question: i have the dti fiber tracts extracted and > computed and already in .trk format. > I was wondering: to bring them back into the template MNI152 space, is > it sufficient to apply the talairach.xfm transformation matrix to the > vertex data, or do i also need to use the m3z files (which look like a > nonlinear deformation field)? > > thanks in advance! > Paolo _______________________________________________ Freesurfer mailing list [email protected] https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer The information in this e-mail is intended only for the person to whom it is addressed.
