One final thing: Nick and I found last week that the accelerated mri_em_register_cuda doesn't seem to work prior to skull stripping. I'm going to work on this this week, but if you want to continue using the GPU accelerated binary, you'll have to turn off the FAST_TRANSLATION and FAST_TRANSFORM flags in mri_em_register.c, and recompile. This will increase the runtime to around 4 minutes on ernie, but will give results identical to the CPU code.
Actually, the problems with mri_em_register_cuda appear to be a little more widespread. I'm working on testing this with more brains now (the perils of having only one test case...), and hope to have an update soon.
