[caret-users] Landmark Issue

[Sandoval, Traci I]

They look fine on the inflated surface, but when I draw the other
landmarks then append the landmarks from flattening I get the scattered
border points, then I just deleted the borders from flattening and drew
all six landmarks, but when I open the subjects spec with the colin
atlas to run spherical surface deformation, I get an error that states I
don't have the same number of landmarks on my subjects vs the colin
atlas. I was thinking this was due to the splattered border points I had
been deleting. I feel I am missing something in this process. 

Also, when you say nibble away, are you suggesting that I can just clean
up the splattered border points by deleting the points individually?

Thank you for all your help. Traci

The borderproj looks suspect to me, too, but it is better to view the 
from flattening borders on a medial view of the inflated surface.  These

are typically appended AFTER you have drawn the other landmarks (CeS, 
sylvian, and aSTG) on the flat map and projected them.  At that point, 
you don't really need the flat map anymore, and can switch to the 
inflated view; append your flattening borders; and nibble away.

When you view your from flattening borders on the flat map, you lose 
points along the cuts -- sometimes too many along the medial wall
dorsal.

But none of this explains your scattered border point problem.  Still, 
humor me and look at them on the inflated.
