Hi There,

I would to understand that warning below that appears only when I use
verbosity 1 with leap. The leap commands follow:

verbosity 1
source leaprc.ff99SB
prot = loadpdb ProteinAmber.pdb
solvatebox prot TIP3PBOX 10.0
addions prot Cl- 4
saveamberparm prot Protein.prmtop Protein.inpcrd
savepdb prot ProteinNAMDpdb
quit


Building improper torsion parameters.
 ** Warning: No sp2 improper torsion term for C*-CN-CB-CA
        atoms are: CG CE2 CD2 CE3
 ** Warning: No sp2 improper torsion term for NA-CA-CN-CB
        atoms are: NE1 CZ2 CE2 CD2

Many thanks in advance,Alan
