Liz, to be precise, this is true for the standard FS stream. The longitudinal stream is different, as in FS 4.4 the base actually lives in two similar, but slightly different spaces, because the template is created for T1 and recreated for the norm.mgz. The aseg is in the space of the norm and th

Hi Liz, the registrations are stored in baseid/mri/transforms look for files baseid_to_tpNid.lta and the inverse tpNid_to_baseid.lta (which is the map you are looking for). These should align all your TPs to the base space. Best, Martin On Mon, 2009-08-03 at 16:19 -0400, Elizabeth Selgrade wrot

Hello FreeSurfer Users, I am using the longitudinal stream to look at four timepoints/subject, and I'd like to transform all of my timepoints to the base scan's unbiased space so that I can calculate ROI volume overlap. I have been using tkregister2 to calculate the transform from my scan.base.lo

Hi, actually in the newer FS versions (don't know when it started), the cortribbon is part of autorecon3. In those cases all that is necessary is to rerun the final steps: -cortribbon -aparc2aseg -wmparc Martin On Mon, 2009-08-03 at 14:18 -0400, Nathan Dankner wrote: > Hello all, > > I’ve recen
