Hi Bruce,
thanks for your fast reply! The thing is, that I want to work with the cortical-thickness values directly in matlab, but when I use the read_curv() and read_annotation() functions I get different numbers for vertices for different subjects. The goal is to represent each subject by a feature-vector of same size, containing the cortical thickness values with the intention to use various dimensionality-reduction methods, e.g. PCA. I hope you can follow me,
cheers, Matthias

Hi Matthias
that is done as part of the recon-all process. You can do easy group analyses in qdec.
cheers Bruce

Hello everybody,
I ran the recon_all routine on a number of images of the ADNI database. The goal is to extract first of all the cortical thickness values. In order to compare the values in a classification process, eg. Alzheimer vs Normal I want to register all images to a template subject. Does anybody know how to achieve this?
Thanks in advance,
