Hi Bruce!

Thanks for the fast response. I used the current stable version 5.3.0.1 (freesurfer-Darwin-lion-stable-pub-v5.3.0.1). So I will try as you have suggested ...

Best wishes,

Lukas

Hi Luke

what version of FS are you running? We see significant speedups. Try running top in a unix terminal and seeing if the cpu usage of mri_ca_register (during autorecon2, the longest single step) is morethan

100%
