Freesurfer devs,
Are the CUDA binaries still being developed in FS6? Are they compatible with the CPU only versions? I remember asking questions about this a while ago and apparently the cuda binaries were no longer being developed in favour of openmp.
Thanks in advance,

I try to provide what support I can, but the CUDA versions are not a priority.

Richard,
I understand they are not a priority. But are they compatible with the CPU versions? Should we be using the CUDA versions if they aren't guaranteed to be up-to-date?

I haven't run any comparisons against the CPU binaries recently. And if any extra pipeline stages were added to the CPU versions, I haven't ported those to CUDA either.

I have tested a recon-all -all CPU and GPU with and without the -hires option and everything seems to run fine. So at the moment they seem to be compatible or at least the GPU version doesn't crash. So that is ok.
Thanks for your time.

If you do come across substantial discrepancies, please let me know, and I will do my best to resolve them.
