Hi Kelly,
sorry, I meant to answer. mri_extract_label will make a binary ROI out of
the aparc+aseg which you can use as an ROI. The indices for the different
structures are in $FREESURFER_HOME/FreeSurferColorLUT.txt
cheers,
Bruce

Hi, Freesurfers
Dear Mr or Ms
Is there any way that we can obtain curvature value of the pial surface? I am
not sure whether lh.curv is the curvature file that I want. How can I calculate
the mean curvature, Gauss curvature of the pial surface and the GM/WM interface?
Is there any built-in function in
Thanks Pedro, I was just thinking about it.

The current version of Freesurfer calculates numerous curvature-based
functions by default in the recon stream. If you look in the surf
directory for a reconstructed surface, you'll see several curvature
files that end in *.crv.
By default, these are created for the gray/white junction surface
When I compare the thickness measure among subjects, I have to resample and
smooth the thickness, so that each data have the same number of vertices and
which are in correspondence with one another across subjects.
Now I have .curv files or .sulc files for each subject and would like to make
yes, you can. There's no right answer for FWHM, but people usually use
5-20mm.

By the way, could you recommend me relevant papers that calculates the

Check the Freesurfer wiki... Our papers on curvature methodologies as
well as wavelet decomposition have pdfs available.

Hi,
I was wondering if there was a way to compare t1 or t2 maps between 2 subjects
using the volume brain as opposed to the surface brain.
To be specific I have two brains which are T1 maps. I want to see the
differences in T1's between the two brains. How would i go about doing this.
I hope
