Hi Bruce
I found some filled-in occipital horn and some in the anterior parts. I can upload nu.mgz and aseg.mgz for a subject with problems with lateral ventricle.
Cheers Knut Jørgen

Hi Knut
where is it being filled? If it is the occipital horn we may soon have a patch for it

Hi Are there any options that I can use in Freesurfer 6.0 that can prevent lef t lateral ventricle from being filled with WM? Should I send the MPRAGE seq uence information? Knut Jørgen

Putamen should be smaller because we now try to remove claustrum. Small structures may have some large percent differences. Some structures are not that meaningful (like the CC because it has no real boundaries). The left lateral ventricle may be a problem. I've seen cases where it totally gets filled in with WM in v6. Others are hard to define -- when I would look at the scans there would not be a good case for rejecting one and accepting the other (eg, pallidum and thalamus don't have good contrast at typical mprage acq parameters).

When I ran Freesurfer 5.3 and Freesurfer 6.0 I ran with default settings us ing this command. recon-all -s (id) -all for both Freesurfer 5.3 and FreeSu rfer 6.0. Are these differences larger than one would expect? I think that 100% may b e a little high? The difference in volume between Freesurfer 5.3 and Freesu rfer 6.0 is shown in the table below calculated using asegstatsdiff.

I have compared the aseg volume between FreeSurfer 5.3 and FreeSurfer 6.0 w ith asegstatsdiff from FreeSurfer 6.0 for each subject in my data set. I ha ve enclosed the range for some of the volume. I found the largest differenc es in subcortical structures, especially in Corpus callosum(CC). I found th at FreeSurfer 6.0 CC posterior volume was 525.51 % larger than in FreeSurfe r 5.3. Nevertheless, these differences were much smaller for lhCortex, but ?? ?also here FreeSurfer 6.0 was on average larger than FreeSurfer 5.3. I ran t he FreeSurfer 6.0 using the same option as FreeSurfer 5.30. Both versions o f FreeSurfer were run on Centos. I am also enclosing a table with mean values along with min and max for differences between FreeSurfer 5.3 and FreeSurfer 6.0 aseg volumes.
