That does make sense Andrew. But would that be the case even if I weren't correcting for ICV? In other words, the analysis works when I don't correct for it. The GLM still looks for variance in group differences regardless if you're correcting for something or not...right? From: freesurfer-bo

Hi Andrew, the values I'm using are already mean centered -- similarly, I've never been able to use the full ICV values. Even with David's suggestion of reducing the number of digits (effectively making the numbers smaller), it still doesn't work... Gabriella From: freesurfer-boun...@nmr.mg

Try mean centering your ICV values (I.e. Subtract the mean value from each individual value). This has worked for me to bypass this error. -Andrew From: mailto:freesurfer-boun...@nmr.mgh.harvard.edu>> on behalf of "Hirsch, Gabriella" mailto:gabriella_hir...@meei.harvard.edu>> Reply-To: "frees
