Hi Doug,
Thanks you for directing me to my mistake in step 3 (see below new cmd line
in step 3). What I did is the following -
1) dt_recon --i /usr/local/freesurfer/subjects/Anatomy0981/DTI/I160.dcm --s
Anatomy0981 --o /usr/local/freesurfer/subjects/Anatomy0981/DTI --b
/usr/local/freesurfer/subje
You must have already run this subject once with an expert-options file?
Once you've already run recon-all once on a subject with an expert-options file, you don't include it again in future invocations of recon-all. The expert options that you've previously used will automatically get used
it's just a measure of how far each point is from the sphere that we use
to guide some of the spherical transformation. It is a perfectly normal
part of recon-all

Hi Michael
I believe it is telling you that once the file expert.opts exists in the
scripts dir of a subject it will be used by default, and you don't need

Hello Freesurfer Expert,
Can you share the freesurfer sample named *bert* information such as
age,M/F and other details.
Thanks in advance,

1) Use the feat2surf script
2) I have not used mris_pmake myself. I'm guessing it will *work* on the
sphere in that it will return a path, but the distances between vertices
have no relationship to anatomy. It might fail on a flat map because it
is a patch.

Dear Surfers,
At moment I'm dealing with a huge dataset, preprocessed (with and without

Hi,
I'm testing mri_convert for our dicom conversion needs; one thing that

that?
Alternately, if there were a way to make it use stdin, I could just

those are eye sockets not brain. If the surfaces don't include them then

I would use step 3 for the wmparc instead of vol2vol.
you need both --seg and --seg-erode
--seg-erode 1 --seg

Just to get some comparative result with subject which we have.

Hi Amy
if you run it with "&" at the end of the line, it shouldn't end when you
close the terminal window. Of course it will stop if the computer goes to
sleep though.
To rerun a recon that has partially finished, try using the -make all

Hi!
If the cortical surface outlines are fine, but there is an overinclusion of
brain volume during segmentation, how should I fix this? Can we calculate
brain volume based on the cortical surface outlines -- if so, how?
Thanks!

Hi Christina
if the aseg is incorrect but the surfaces are right, then you don't need
to worry about it. This is the reason we typically use the surfaces
instead of the aseg for things like brain volume/cortex modeling.

Hi Caspar,
I can't address your question regarding a specific tool, but wanted to mention a note of caution.
You need to make sure that you scrub any identifying info from Siemen's custom DICOM fields (not just the obvious public DICOM fields).

Thanks a lot!! I have a follow up question:
We use the command

to output the subcortical volumes (and other whole brain volumes) to
