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,
