Could you please give me the unit measures for each of these parameters:
Volume: (is it measured in mm3?)
Maximal Depth
Hulljunctions (length)
Surface
or you can tell me where I can find this info? I already searched in your site and in Riviere's thesis but I could not find it. (maybe because somethings are in french
thank you, nat
parameters from morphometry statistics

Hi,
Yes, the volumes are in mm3 and surface is in mm2, and lengths are in mm. You have a very short doc of the measurements in brainvisa, on the morphometry process, but I know it is too succinct to get a good idea.
Just be aware that the sulcus measurements are done on the "skeleton" of the sulcus: a 1 voxel deep surface going from the brain hull inside the fold: it will actually give you information on the deph of a sulcus, but nothing about its cortical thickness or opening/LCR volume (until we work on it agin...).
