Hi Han

the files ?h.curv contain the spatially smoothed mean curvature. You can compute the mean or Gaussian (or principal) curvatures of any surface using the mris_curvature command.

Dear FreeSurfer Team,


I heard that FreeSurfer could calculate the Gaussian curvature and Mean
curvature by vertex level.

Do the computed curvature values be saved as the subject/surf/lh.curv  or
rh.curv  files?


When I prepared the generated mass-univariate data, I used the mris_preproc
with [--meas curv] option, not [--meas thickness].

mris_preproc --qdec-long qdec.table.dat --target study_average --hemi lh
--meas curv--out lh.curv.mgh

I wonder this option is right usage to analyze the cortical curvature. And I
wonder the 'curv' is what specific value is meaning.


If I want to designate the specific curvature values(Gaussian or Mean
curvature ) to analyze by vertex level, how can I use the [--meas] option?


Thank you,

Best wishes,

Han.
