I usually can run one instance of FreeSurfer with 1GB if I use the -no-gut flag I have a benchmark of 4 recon-all running in a 4 Core AMD with 4GB RAM that took only 10% more time than one recon-all alone. 2011/7/6 John Jan Drozd > Hi Bruce, > > Thanks for pointing this out to me about the RAM.

Hi Bruce, Thanks for pointing this out to me about the RAM. I have 8 Gb of RAM. So I guess I can safely run 3 or 4 subjects simultaneously if each subject requires 2 to 3 Gb of RAM. Thanks, John Sent from my iPhone On 2011-07-05, at 6:08 PM, Bruce Fischl wrote: > how much ram do you have?

Sorry, that won't help a single subject much, although there are options to run the hemis in parallel. You can run multiple subjects at the same time, which is what we usually do. Or you can use cuss On Jul 5, 2011, at 5:11 PM, John Drozd wrote: > Hi Bruce, > > Okay, thank you. I understand

Hi Bruce, Okay, thank you. I understand and can see that to do an accurate job, the pipeline must be complicated. I have eight processors on my linux desktop computer. Maybe some parts of recon-all are multi-threaded which could speed things up for me :-) Thank you, John 2011/7/5 Bruce Fischl

sorry, but the majority of the time is required. We're working to speed things up, but it is complicated software with multiple nonlinear warps, segmentation procedures, etc Bruce On Tue, 5 Jul 2011, John Drozd wrote: Hi Bruce and Pedro, Thank you both for sending me your suggestions.
