External Email - Use Caution        




Hi!I have a macbook pro MY 2014 with a Intel Core i7(quad core,2.7 ghz) and 16 gb of ram with El Capitan.This Macbook to run recon-all it takes 47 hours with -openmp 8 flag.

A Dell with Intel Core i7 3632Q,8 GB RAM DDR3 1600mhz with Linux  takes 8 hours...The same Dell on windows with linux virtualizated takes 13 hours.

Why recon-all on mac is so slow? is the OS?the type of compilator used for each platform?freesurfer not optimized for El Capitan? the architecture of the cpu?

Some Advice?
