Hi, I have a couple questions regarding the -long option.

1) The longitudinal instructions listed in recon-all -help all use recon-all -all -long. If I am only interested in the subcortical segmentation, will the longitudinal processing still work if I only use recon-all -subcortseg ?

2) How long does the longitudinal pipeline take for a) tp1, which has already had the cross-sectional workflow run b) tp2, which gets compared to tp1. I suspect a) and b) are the same, but do they take the same amount of time as a conventional cross sectional run?

thanks, mishkin
