Hi Antonella
the atlas is not guaranteed to be correct. If it were we would just take
the labels from it :) The only way to tell if it is correct is to look at
the segmentations on top of the MR and see if they follow the visible
boundary
To get the surfaces you should do

Hi,
I would like to check if my subcortical segmentation is correct so I was
running:

1). Pial (red line), and white (yellow line) surfaces are shown and I wonde
Does anyone knows which command would exercise the GPUs using CUDA as benchmark?
Thanks,

Hi Bruce,
I forgot to ask why my data does not include an unknown region in my
aparc.stats file? My stats data starts with bankssts region and continue with
caudalanteriorcingulate, etc. Do I need to have the unknown region if I use the
new version of the FS 5.1.0?
Thank you.
Antonella

1. Yes, that's reasonable. You can use .nii.gz and the output extension
and it will automatically gzip compress it.
2. No, I don't think so.
3. The only real way to check is visual inspection.
cheers
Bruce

I will graetly appreciate if you can help me with the following questiosn:

question, the only thing I know is that my MRI data contains more
sequences/series (3DAx_T1, 3DSag_T1, Ax_Flair, Ax_PD, Ax_T2, BO

Hi Yolanda, don't use thmax (it will exclude everything with a sig>7 --
not what you want I assume). That command otherwise looks right, but it
won't correct for multiple comparisons. You can run
mris_anatomical_stats on the output label to give you the stats you want.

Hi Chris, mri_surfcluster should output coordinates in "Talairach" space
(The newer 5.1 version uses MNI305 space). Internally, we always use
MNI305 space. To report "Talairach" coordinates, we then apply a
transform (http://www.mrc-cbu.cam.ac.uk/Imaging/mnispace.html) to give
particular values
No errors, I hadn't actually tried it because everything else was so
hemispheric based, and I didn't want to just blindly try it and be unsure of
the data I got out. So I should be able to (in surface space) draw a LH and

Hi Knut, why does the color bar need to change? It should be symmetric.
Do you mean that you want the color bar to flip?

Hi Katie, it should not matter that they are across hemispheres. Are you
getting an error?

It won't give you talairach coords in the label file, it will give you
MNI305 coords. Use the View->Information in tkmedit to get MNI305 coords.

Hi Carolina,
the yellow line represents the gray/white boundary, and so presumably
should follow the bottom of the heterotopia. If it is large though, it
may be difficult to obtain an accurate boundary since it breaks many of
our assumptions (e.g. max thickness, sharp intensity gradient at gra
Hi Silvia,
it is never a good idea to mix versions and we did not test any such
combinations. Also because 5.1 is much better than 4.5 I would
definitely recommend to rerun.
However, I still believe that it should be possible to use the 5.1
post-processing scripts to e.g. create rate maps for ea
Hi Natalia,
/TemplateSub1/surf/lh.thckness.fwhm10.fsaverage.mgh
there is an 'i' missing in thckness (but that might be just a typo).
also this is a regular thickness file. You cannot analyze the thickness
in the base. That is meaningless, you need to select one of the other
files in qdec, e.g. t
Hi Bruce,
Yes, it should be classified as a gray matter, if I save a point of an
heterotopia in the tkmedit and then open it in tksurfer the point showed at
the inflated surface correspond to that point or to the projection of the
heterotopia in the cortical surface?

Dear freesurfers,
