Re: [Freesurfer] reg-feat2anat: a problem!
Dear Doug, The determinant sign is negative for both example_func and orig.mgz (-73.6 and -1, respecitively). The files differed also in their format, type, vox2ras-fsl and orientation, but I guess it is ok. My feeling was that flirt is unable to fit the brain given the maximum angle of rotation 90, so I doubled this using: re-feat2anat --dof 6 --maxangle 180 --feat run1.feat --subject xx I tried this on several subjects and the registration looks very good: I would not make it better manually. Can I assume it works now?

Re: [Freesurfer] reg- feat2anat error-problem
It sounds like something has to be fixed. Is the example_func to standard space registration correct? If not, then you will need to fix it. That registration is purely FSL. doug uzay emir wrote: Hi, Orientation problem is outlined below. 1-When the target in coronal view, movable(example_func) is sagital. 2- When the target is in sagital view, movable is coronal. 3- axial view is teh same both movable and target but The problem in this situation is that there is an angle between movable and target. I followed all the steps. Right now should I expect that reg-feat2anat solves the big problems or should i have to register manually with tkregister2?
