Hi Dorsa, well visual inspection is always a good indicator. Also you could have a look at the QA Tools (https://surfer.nmr.mgh.harvard.edu/fswiki/QATools). I haven’t tested them though.
Other than that, I wouldn’t know of any objective method to validate your results. Probably someone else can jump in on that. Best, Falk P.S. Be sure to also reply to the list also.

I was actually able to get results using my high resolution images without changing their resolution. Is there any way to validate my results to see if I have good results?

With FreeSurfer v6 this workaround will not be necessary anymore, as the processing pipeline has been updated. If you want to, you could also try out a recent developer build. However, it is still under development.

Juli 2016 18:06 An: Freesurfer support list Betreff: [Freesurfer] question about voxel size Hi, I have a T1 weighted MRI which I want to segment using Freesurfer. The voxel sizes are 0.48*0.48*0.48. I read that the ideal voxel size for freesurfer is 1mm^3. Is there any manual adjustments that I can make to get good results with my 0.48 voxel size images? Thank you Dorsa Ghaffari
