Hi Ranila
the different versions contain slightly different algorithms, so why
would you expect them to be the same? With 20 subjects you may be at the
edge of having enough power to see a significant effect.

External Email - Use Caution
Hello Experts,
I was working with some data pre-processed using freesurfer v5.3 - i think this
was done on linux.
Recently I pre-processed the dataset using v6.0 on an imac. I extracted
cortical thickness and
surface area from both hemispheres. The data is different for each version.
What worries me is that
I am correlating the neural metrics with some behavioral data and this gives me
different results.
My sample size is only 20.
Some advice would be very helpful.
Thanks.
Cheers,
Ranila
