Nic,

Concerning Ubuntu and Freesurfer, we have not used that OS directly ourselves, but I believe people on the list have used Ubuntu and Freesurfer. I think there were some library issues, but nothing that was a show-stopper or overly difficult to fix.

We have many Xeon dual core machines in use here, so Freesurfer should run fine on that. Your plan run a recon-all on each processor is fine.

Hi,

I am about to order new hardware that will be used to process scans with freesurfer but also for processing with other packages. Has anyone had experience with the combination of Xeon quad-core processors, Ubuntu, and Freesurfer? And if yes are there any issues I should be aware of?

To my knowledge one Freesurfer process cannot run in parallel on multiple processors but I intend to process multiple scans simultaneously, hence the selection of a multi-core architecture. If somebody has some experience of the difference between 2.33 GHZ, 2.66 GHZ, and core-duo 3.00 GHZ I would also be interested to hear about it.

Thanks

Nic
