Martin,

The safe option is to run -autorecon1 again for these subjects. The new stable release is careful to keep all edits (in fact, you have to tell it not to keep edits via the -clean flag if you don't want to retain edits).

Manually removing the optic nerve will not decrease processing time, so I would not bother.

Hi, I have processed some of my subjects on a previously released dev-version (20060210). I have changed to the new stable release. Do I need to run the -autorecon1 step again, or will -autorecon2 and -3 suffice to bring the previously run subjects up to date? (the brainmask-volumes have been edited, so I'd like to keep these changes)

Another question; if I run the -autorecon2-wm flag, will I save a lot of computing time if I manually remove the Optic Nerve before doing so?

Thanks,
