Dear all,
        
      I want to using charmm22 parameters to calculate vdw 
interaction. 
                  EMIN            Rmin 
                 (kcal/mol)        (A) 
N*                 -0.0900         1.830 
P*                 -0.100         1.900
M*                 -0.001          0.650
S*                 -0.043          1.890
AR                 18.00           1.88

However,I do not know N*,P*,M*,and S* correspond to what. Could 
anyone tell me the meaning of the atom type with star.

Yours sincerely
Liang Shide
