Hi FreeSurfer Experts,
Just a quick question: Generally speaking, assuming everything else remains the same, are subjects run through a CUDA-enabled recon-all comparable to subjects run through recon-all without CUDA?
Thanks, Marcus

We assume that.

There are differences, which are inevitable as a result of running the calculations on a different device. I've been comparing results as I've converted things, but only in a mathematical sense (and from individual routines). We're currently working on analysing complete asegs, so we can quantify the differences anatomically.

Thanks for the info. Richard, it would be great to hear what you find.
