What is the best reference regarding the calculation of surface area and
surface curvature and are there any studies looking at the reliability of

I am running qdec on a Mac Pro OS X 10.5.5 with dual quad pentiums mirrored
RAID and 16GB memory.
I have followed the instruction for creating the qdec table, loaded the data
in successfully and requested an analysis with two continuous variance. The
following is the final output before it crashes
Is there any documentation regarding the specifics of the process of subject
averaging. Specifically, I am unclear on how the parcellation and cortical
thickness is derived for the average subject. Is this information
averaged from the input subjects or is it derived from the newly
formed average v
While running freesurfer I obtain the following error message

For some reason my mris do not have a transforms/talairach.xfm file (created
in old version of freesurfer)
Is there any way of creating this file without going through the entire
freesurfer workflow?
Thanks
