External Email - Use Caution Hi Dawn,
See https://surfer.nmr.mgh.harvard.edu/fswiki/recon-all#Step-wiseDirectives-1 for an approximate beakdown of computational time per step. The parallel flag in FS v6 will decrease this to about 3 hours total on a 4 core machine. (time varies depending on your workstation, surface defects, etc; if using a cluster, check with network admins about using -parallel) Volume, thickness, area, curv are all going to be seconds to minutes calculations and would not meaningfully impact your recon-all time. -Adam On Fri, Nov 16, 2018 at 3:47 PM Dawn Matthews <dmatth...@admdx.com> wrote: > External Email - Use Caution > > Dear Freesurfer team, > > > > Thank you for your continued efforts and advances on the Freesurfer tool, > which have benefitted the community and quest for therapy advances.
