External Email - Use Caution

For 2 subjects that is what you can do.

If you have a lot more, I would suggest to have a look at GNU Parallel [1]. It's also available in the Ubuntu package system.

Best,

Tim

Hello FreeSurfer Developers,

My computer doesn't support cuda. To speed up data processing, could I open two terminal, and in each of them, I first runing:

$> export FREESURFER_HOME=/usr/local/freesurfer $> export FREESURFER_HOME=/SetUpFreeSurfer.sh $> export SUBJECTS_DIR=/usr/local/freesurfer/subjects/

then running: recon-all -s sub-01 -i sub-01_T1w.nii.gz -all (for terminal 1) recon-all -s sub-02 -i sub-02_T1w.nii.gz -all (for terminal 2)

Thanks.
