Hi Bruce
I have uploaded the subject as subject_7.tar.gz and subject_7.zip at transf
er/incoming on surfer.nmr.mgh.harvard.edu
I can also upload the same subject where I used fs53.
Thanks

Hi Knut
the best would be if you can just tar and gzip the entire subject dir
and upload it according to these dirs:

Hi Bruce
Where should I upload orig.mgz, nu.mgz, aseg.mgz and
voxel cords?

Include the orig.mgz and voxel cords and I'll see if I
have already fixed it

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 ventri
cle.

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

This is a test we do before we release. The averages
don't look out of
line. 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).

Dear FreeSurfer experts,
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.

Dear FreeSurfer expert,
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

at FreeSurfer 6.0 CC posterior volume was 525.51 % larger than in FreeSurfe

but
