Hi Doug, Thanks for the follow up. Do you recommend using a covariate such as mean thickness or is a covariate not necessary for cortical thickness analysis? Thanks, Ajay On Thu, Sep 8, 2016 at 2:00 PM, Ajay Kurani wrote: > Hi Freesurfer Experts, >I am comparing a control group and 2 pa

thickness does not scale with ICV (surface area does). Not sure about LGI On 09/08/2016 03:00 PM, Ajay Kurani wrote: > Hi Freesurfer Experts, >I am comparing a control group and 2 patient groups (HC vs Group1, > HC vs Group2, Group1 vs Group2). I am interested in seeing what is > the most

Hi Freesurfer Experts, I am comparing a control group and 2 patient groups (HC vs Group1, HC vs Group2, Group1 vs Group2). I am interested in seeing what is the most appropriate covariate to use for both a cortical thickness analysis and LGI analysis. I do not expect major changes in brain sha
