You can run the old command and then start the processing from that step on I think. On Mar 30, 2011, at 4:23 AM, Nikolas Borrel-Jensen wrote: > Hello! > > I have found a solution for the problem causing the bad registration. > > In Freesurfer 5.0, the function mri_robust_template is used

Hello! I have found a solution for the problem causing the bad registration. In Freesurfer 5.0, the function mri_robust_template is used for registration creating the output volume rawavg.mgz when using the autorecon1 flag. It turns out, that in Freesurfer 4.0, this step is performed by the funct

I'm not sure about the mri_robust_template issue, but you can check the orientation by loading it in tkmedit. If the axial is axial with (nose up) and the sag is sag (with nose to the right), then the qform is right (assuming that LR is ok, which you can't check based on the direction of the no

Hi! I am having some trouble with the motion correction step when having two volumes (NIFTI files). The average volume has not been determined correctly due to a wrong orientation/registration of the two original volumes (see http://freesurfer.nikolasborrel.com/bad_registration.tif). Is the proble
