Hi Lukas,
I wouldn't mix versions. The newer ones have many nice features, particularly in the visualization, but if the old one does everything you need, then you're probably okay.

Hi Bruce, many thanks! Actually, I wanted to try the examples first, play around with it and than start to do the actual analysis. By the way I discovered today that I use a rather old freesufer version (20030724) and I have to admit that I did not update to the latest version. So far I have prepared about 50 data sets. I wonder if I would have to do eveything once again after applying the update??? Do I have to update? Best wishes and many thanks!

Hi Lukas,
I've attached a gzipped tar file with ?h.white, ?h.pial, ?h.curv and ?h.sulc. Please be careful interpreting results on average7! The only
truly
valid way to display things is on the inflated surface with an average curvature map overlaid. You can use mris_average_curvature to build an average of the subjects in your study.
cheers, Bruce

Hi freesurfer folks,
I try to run some example cortical thickness calculations as outlined in mris_glm --help. The first step (read thickness maps, smoothing and resampling to average7 as well as saving the regression coefficient works fine, however it crashes with the complain that it does not find: /data/FreeSurf_Subjects/average7/surf/lh.white when testing the data for any effect. I wonder, where I could find the surf/lh.white (and surf/rh.white)?
It is
not in the diectory where it is supposed to be.
Many thanks for your help in advance...
Lukas
