[caret-users] draw borders for spherical registration

[Julia Molony]

I'm attempting to go through Caret's spherical registration stuff but  
first I need to work out how to draw all the borders.  I'm following  
the 5.5 tutorial and I'm stuck trying to draw the medial wall  
borders.  When I open the draw borders dialogue, choose the border  
name, set type to closed and dimension to 2D, and press apply, I  
can't draw the border.  I click on the sphere and hold the left mouse  
button and nothing is drawn.  Any ideas on what's going on?  I  
checked the D/C to see if "show borders" was selected and it is.   
I've drawn borders in the past with no trouble, so I'm not sure  
what's happening here.

Also, what does it mean in the "Flatten Full or Partial Hemisphere"  
box when it says "Smooth Fiducial Medial Wall".  It looks like this  
smoothing is causing distortions in the sphere.  It makes the sphere  
look sort of swirly around the medial wall area.
