i may just have the program you are looking for.  i've written it a
while ago, for analysis of interhelical angles in a protein
(J. Mol. Biol. 323 (2002), 99-113), and applied it again recently on a
system exactly like yours, ie., lipid, peptide and water
(Biophys. J. 88 (2005), 939-952).

the program is available, contact me off-list.
