Re: [Freesurfer] Specification of computer

Hi Bruce,

So, I am not sure if I understand correct. Suppose, I would like to run 4 subjects simultenously, I have to run the recon-all command of each subject on each terminal with -openmp. Otherwise, is there any other options to run 4 subjects in one terminal.

Thank you, Aziz.

yes it does, and it should significantly reduce execution time unless you don't have multiple cores

Does FS6 support the 'openmp 8' flag? I tried to use this flag with 'recon-all -all' on FS6, but it took longer time for only one subject.

Thank you, Aziz.

  with multiple course you can specify -openmp 8 for exmaple to use 8

cores, which speeds things up a lot. It also depends how many recons you will be running at the same time. A 16 core machine with 64G of ram would be able to run 4 recons in a few hours each.

        Hi experts,
        I would like to find a new high-performance computer to

run the reconstruction process in Freesurfer. Currently, I used a single computer (Intel core i7, RAM 8MB) to run the commands (e.g., 'recon-all -all' ) that spent average time 7-9 hours per one subject data.

        Please let me know what the best spec of the computer that

can reduce the time to 2-3 hours (if possible).

        Thank you,
        Aziz
