Dear Amber user,


I am using cpptraj for trajectory analysis. when calculating
SASA using LCPO method for my metalloprotein found this warning


                          BEGIN TRAJECTORY PROCESSING:
.....................................................
ACTION SETUP FOR PARM 'cd_cdcj7.prmtop' (1 actions):
  0: [surf :1 out surf1.dat time 0.002]
    LCPO surface area will be calculated for 19 atoms.
    19 solute atoms.
Warning: Using carbon SA parms for unknown atom 1061 type Cd2+
Warning: Using carbon SA parms for unknown atom 1062 type Cd2+
Warning: Using carbon SA parms for unknown atom 1063 type Cd2+


LCPO method does not have the parameters for cadmium ions so it assigns
carbon SA parameters to compute the SASA. I want to know what kind of
parameter i need to add and in which file ? kindly give me your valuable
suggestion.




*Thank You and Best Wishes*
