[AMBER] Atom mask corresponded to first or last residues

Dear Amber users!

I would like to perform some basic structural analysis considering
only small fragment of the protein corresponding to the 15 residues
located either in the N or C terminal part. Could you suggest me a
atom mask than could select N first or N last residues (without
definition of the residue numbering) which could be used e.g. for
Radius of Gyration calculations:

# calculate rG of the last 10 residues

rog rg Ntermi :-10.CA out output.xvg time 0.05

Many thanks in advance

Enrico
