Dear Nick,
thank you for pointing me out the bbregister problem which is causing FLAIRpial
to fail in this case.
I have looked at this particular step and found that the problem is with
-init-fsl flag, where initial flirt registration (via fslregister) fails in
these data (in contrast to FLAIR
Dear Freesurfer experts,
I did the retinotopic mapping analysis followed by
https://surfer.nmr.mgh.harvard.edu/fswiki/FsFastIndividualRetinotopyAnalysis
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

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
later, there is lot's of reasons, a brain can look larger:
- less motion artefacts
- better hydration leve
From an analysis standpoint, it is not a problem. You'll have to decide
if it is a problem from a psychology point of view.

Hello Freesurfer team,
I've been previously learning freesurfer by going through the individual
recon-all commands listed on the freesurfer website v5.3 table here:
http://freesurfer.net/fswiki/ReconAllTableStableV5.3 and
recently just ran through the recon-all autorecon steps 1, 2 and 3.

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:
freeview nu.mgz -p-labels posterior_left_* posterior_Left-Hippocampus.mgz
-p-labels posterior_right_* posterior_
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
correct for brain size variability in the cortical
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 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
10 matches
