Thanks Andreia, this does appear to have worked. Please forgive my
ignorance but I do just want to double check two things;

hemispheres of the cerebral cortex only based on the pial surface, whereas

/"assign to each voxel the label with the highest posterior probability"

I've found that this is not the case with the posterior_*.mgz files

Hi again, Luigi,
this sentence that you wrote summarizes everything pretty well:
"I think that the posterior files outputted by freesurfer are missing the final
step of required to each voxel to the single label with the highest posterior

We will implement this in the next FS release.

I just have a final consideration.
Whenever this last step will be implemented, there will still will be the
problem of how to binarize those subfields in a way that makes sense.

non-zero voxels will always overesti
Hi Will,
Just to clarify, what version of FS are you using? I think it might not be
5.0 and I don't know if everything aplies if we are using different
versions.

for the aparc, DK altas). The second set provides the surfac
Dear Freesurfers,
After running recon-all, the wm surfaces are too close to the pial surface,

How can I shrink the wm surface?

mris_expand may do what you want.
You can use it to shrink or expand the points on a surface by a fixed
percentage or a fixed distance.

Dear Freesurfers,
Is there a way of calling freesurfer-scripts from within MATLAB?
I know there are some setups needed to make MATLAB understand where it can
find the commands (I have done this before with FSL).
I am using bash, and when I type the Freesurfer commands in a terminal by
hand, they w
Hi Barbara,
You haven't told us which OS you use.
For example in Mac OS it is necessary to start up MATLAB by typing matlab
into the X11 terminal, otherwise the system OS will not recognize the
commands given via matlab (e.g. system('mycommand') .)

Hi Joann
it looks like some white matter is not being identified in the ?h.white
surface. You need to diagnose why this is happening. It's probably an
inaccurately corrected topological defect. Have you gone through the
tutorials? You will likely need to add some wm voxels back in. If you

Dear FreeSurfer experts,
I get a new message when I use "mri_convert" command to convert dicom to

create mgz file, and goes to infinite loop.

This is tough to interpret, but basically, yes it would be
0-.004mm2/year. It is not quite right to say that it is at that vertex
because of smoothing, but in that area. It is also hard to say what the
total change would be for a cluster. One could sum the changes over the
cluster vertices, bu
Why do you have your activation in a .w file? If you can save it as
.mgh, then things get a lot easier. You can convert it to mgh using
mri_surf2surf. You'll need to convert the thickness to mgh with
mri_convert lh.thickness lh.thickness.mgh. Then load the two mgh files
into matlab, eg,

That means that you need to add something like

Can you please attach the trac-all.log file, which has the entire output
from beginning to end? Ofter something goes wrong earlier that causes the
program to fail later in the process.
Also, we'll need your original configuration file. Thanks!
