Sure, sorry I should've put all of the information on here originally. We bought a new MacBook Pro. The version of FS (5.3.0) is the same on both computers, and the machines are the same in terms of RAM (the new one actually has a faster processor), the only difference is the older machine has OS 10.9.5 and the new one has 10.11.1. We ran the same subject on the different machines and got the differences in time (the older one took about 6 hours, and the new one taking 30+ hours). It is not a bad brain that we processed, a little older but in pretty good shape and it is a 1mm isovoxel scan with good resolution etc.

Please let me know if you have any information as to why this would be,

Thanks,

Marissa

Hi Marissa

we can't help unless you give us more details. What processors/memory was there on the old computers? What is on the new one? Have you tried running the same data on each to get comparable timings?

cheers

Hi Freesurfers,

I've recently downloaded free surfer onto a new computer. It's working
correctly, but the running time for the recon-all -all command is 30-50
hours. This is in contrast to when I've used free surfer on previous
computers where the run time was 6-12 hours. I'm wondering why this would be
the case and if anyone else has run into this problem.

Marissa
