[Chimera-users] automated selection of most N-terminal residue in model

This atom specifier will select the nitrogen of the initial residue of  
each chain:

	protein & @n & @/idatmType=N3+

It kind of sounds like you may already know your way around a script.   
Let me know if you need more help with the scripting than the above.
