[caret-users] too many crossovers

[Bela Bhatia]

Donna,

I checked by spinning the borders and they look ok - no kinks or sharp 
turns.
I have uploaded 2 zip files
NPRArchive.tar.gz
Right_Hem_Atlas_11_final.tar.gz

What are the variables that affect crossovers during spherical 
Registration?

Thanks for your help!

Bela
