Thank you Bruce,
Sorry for the delay, just getting back from Germany.
I have uploaded a PPT describing the issues that I am having - see notes in the PPT. They are under transfer/incoming, a TGZ file and a PPTZ file both dated today.
I also uploaded the data directory from the qdec evaluation.
Thanks, James

Hi James
sure, we'll take a look. Can you clarify what you are doing though? When you say there is decreased thickness what is it relative to? Information on uploading is here:

Hello,
I'm trying to figure out why I am getting differences in apparent cortical thickness between BrainSuite11a and Freesurfer.
I have a patient scan - high res SPGR BRAVO off a GE 1.5T scanner.
In BrainSuite, their are marked decreases in cortical thickness that is
consistent with the patients TBI.
In FreeSurfer, the changes are quite bit more subtle, and when I compare this one image to a group of normal images (the feature that is very attractive about freesurfer), I do not get anything close to what I would expect.
Is there a way to post images? Or perhaps links to images on another site?
I am not sure where to begin to search for answers as to why I am getting these differences.
I would be happy to answer more questions - I likely have not provided enough information.
