Sorry -- I should have mentioned that you can save the resulting
surface_shape file in ASCII form, and the corresponding columns will
include a scalar value for each node. After stripping the header, you
can import this file into an external application for statistical
processing, if desired. Note also that Caret includes several useful
utilities (e.g., mathematical operations) under the Attributes: Surface
Shape menu.

Hi Dr. Giffard,
Make sure you have the "source" surface (e.g., flat or inflated)
loaded in the main Caret window. Make sure the "reference" (e.g.,
fiducial surface) is loaded; it need not be opened in a window.
Then, so Surface: Measurements: Generate Distortion. Select OK.
Then, use D/C: Overlay/Underlay - Surface and make sure Shape is the
underlay (and that no overlays are completely obscuring the
underlay). Select Areal or Linear distortion from the Shape drop-down
menu.
Hope this helps,
Donna

Dear all,
I am new user of caret and I was wondering how I can get a report of the
areal and linear distortions for a determined area (occipital lobe,
temporal lobe ...).
I can obtain a shape displaying these informations but I am unsuccessull
to get any values for nodes.
Thanks in advance for your help
