The Open Science Grid (http://www.opensciencegrid.org) is a federation of university and laboratory HPC facilities which share computing capacity to support science.
We have developed a command line tool "fsurf" you can use from your laptop or desktop computer to submit scans for FreeSurfer processing on these clusters. FSurf allows you to run the standard Freesurfer workflow (autorecon-all) with single or multiple scans. In addition, you can run a single step with arbitrary options. Although only FreeSurfer 5.3 is currently supported, we anticipate adding support for FreeSurfer 6.0 soon.
No allocation is required.
We only request that you cite the OSG in publications that benefit from its use.
