External Email - Use Caution        

Thanks Bruce - getting back to this after quite some time now. I've managed
to make a central sulcus label file following these instructions (turns out
the CS was connected to the Post CS) and run it through mris-register.

I had a couple of follow up questions:
How can I use the results of the above to create a corrected parcellation?
I presume I need to recreate surfaces / labels afterwards - which command
should I use for this?

best
Fraser
