Hi Stefano,
What error do you exactly get when you run the command to visualize the
segmentation? If you didn't get any error message, please bear in mind that,
because it'd loading a bunch of files simultaneously, it takes a while to load.
Regarding B and C: you can extract volumetric masks for
Hi Surfers,
I am using mris_pmake (in nmr-dev-env) to measure the distance between
two vertices. Everything is fine as long as I use just one terminal. But,
to accelerate my analysis, I have divided my analysis into multiple parts
and run each part in one terminal. It means, I may run multip
Hi FreeSurfer experts,
I have a couple quick questions I'm hoping someone can clarify for me;
I am conducting a group surface-based morphometry analysis in all three
measures in 2 groups (patient and control) and am looking for the best way to

Hi list,
I'm using version 5.3 and I have performed hippo-subfields analysis.
A- I'd like to visualize the mask of each subfield on the T1.
In subid/mri, I run the command line above:

Hi Gonzalo,
images across scanners are not comparable. You basically change
everything there is: vendor, field strength.
In addition to that, even if you used the same scanner three years

- better hydration leve
Dear Freesurfer experts,
I did the retinotopic mapping analysis followed by

and view the results by rtview recommended by you. e.g., for subject s03:
rtview --s s03 --rh --polar --real polar/real.nii.gz --imag
