Hi Koen,
As already mentioned, I'm using v5.1.0, Mac Intel
Leopard version.
The voxel values of posterior_left_CA2-3.mgz and
posterior_right_CA2-3.mgz are between 0 and 255,
if that is what you mean by results.
By the way: I always get the 8 lines with invalid
drawable messages from freeview.

OK, I see why this is not working. We've been changing some name
conventions in our internal FreeSurfer repository after the public
release of version 5.1, and somehow you managed to get an incompletely
updated version.
It appears from
ftp://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/5.1.0
I have downloaded the file
freesurfer-Darwin-leopard-i686-stable-pub-v51.0..dmg,
date 26/05/2011.

Dear Freesurfer users,
I've been trying to map a Qdec contrast sig.mgh to the native volume of a
subject using mri_surf2surf (to get from Qdec fsaverage surface to native
surface) and mri_surf2vol (to map from native surface to native volume
cortical ribbon). However, the last step goes wrong: I
Doug or any freesurfer experts can you please answer this question it is quite
urgent:
I have created some manual cortical labels in freesurfer using tksurfer. The
.labels file containing the vertices of the cortical labels does not correspond
to the labels of the pial surface even though they
Hello Bruce,
Sorry--just getting back to this project. The basic problem is that I am
trying to align a cerebellar parcellation with the underlay in tkmedit.
I was working on this with Doug, and his suggestion actually worked, and
now I can't get it to work again (see thread:
Hi Ed,
It seems that the 5.1.0 release for the Mac was composed two days
after the one for Linux, and during exactly those two days one of us
made a change to the file $FREESURFER_HOME/FreeSurferColorLUT.txt.
To correct this issue, please make a back-up copy of your
FreeSurferColorLUT.txt file,
Hi
Can anyone tell me please how mri_label2vol works, I know what it does,
but I need to know how it works to take the FS space to the original
anatomy space: does it do registration or does it use a transformation
matrix. If the latest which one, where can I find it?

Hi Nick,

Hello,
I converted the aseg. mgz files to nii format and created a hippcampal mask
with 3dcalc.
Using AFNI I opened the hippocampal mask as overlay on the brainmask .nii image
as underlay. For some subjects the hippocampus is not at the correct position.
Please advise.
Thanks,
Rashmi.
Hi Rashmi
does it look correct in our visualization tools? If so, you'll need to talk
to the AFNI folks.
cheers

Hi Tina, sorry for the delay. Most of us are involved in the FS

so, then it is not a surface, and I'm not sure what mris_convert would
do with it. I'm
If you pass it a registration (--reg) then it uses that. It can also
compute a registration from the information about the geometry in the
header (--regheader) (assuming that the two volumes share a coordinate
system).

How are you visualizing the results? Can you send a pic? You should be
using tkmedit.

What version are you using? One of our versions had a problem with
creating bad mgzs. You probably don't need to convert it to mgz. Can you
run mri_label2vol with the original nii and see if it works?

We have a large number of subjects that need minor edits (orbital frontal

We have found Wacom tablets are excellent for editing.

Hi Doug-
I wanted to follow up on this procedure and ask for a bit of clarification. As
an extension from Ines' efforts, I believe one can produce a ' lobe+aseg.mgz'

There's a possibility that changes in cortical thickness in

i would think that white matter hyper intensities would tend to enhance
Hi Greg,
I would say there are a variety of possible confounds for cortical thickness
(e.g. changes in cortical myelin content, changes in the closeness of
opposition between grey matter and the dura from brain atrophy), but that
wouldn't be one of the ones I would think of. White matter
