thickening labels within a subject

[Frederic Dick]

Hi

is there an optimal way to project labels into cortex for a single  
individual? I've been using mri_label2label, but it seems a bit strange  
to be moving back and forth from the registered sphere when you're just  
dealing with the same person (e.g., using -srcsubject and -trgsubject  
....)  Also, when I do this, the label actually moves away from the  
white/gray boundary, rather than extending from white through cortex  
(maybe I'm doing something dumb - command is below).  Finally, what is  
the best way of saving these into a volume? I've been using  
mri_vol2roi, but wasn't sure if there's something new and exciting out  
there.

 I'd thought that this had been covered before by Doug G., but can't  
find the messages, sorry!

thanks a lot,

Fred
