hello:

  I am generating a .tpr file for proten/ligand system, but it has so 
much warnings:


NOTE 1 [file md.mdp]:
   nstcomm < nstcalcenergy defeats the purpose of nstcalcenergy, setting
   nstcomm to nstcalcenergy


NOTE 2 [file md.mdp]:
   leapfrog does not yet support Nose-Hoover chains, nhchainlength reset 
to 1

Velocities were taken from a Maxwell distribution at 300 K

NOTE 3 [file complex.top]:
   The largest charge group contains 12 atoms.
   Since atoms only see each other when the centers of geometry of the 
charge
   groups they belong to are within the cut-off distance, too large charge
   groups can lead to serious cut-off artifacts.
   For efficiency and accuracy, charge group should consist of a few atoms.
   For all-atom force fields use: CH3, CH2, CH, NH2, NH, OH, CO2, CO, etc.

Number of degrees of freedom in T-Coupling group Protein_LIG is 9475.34
Number of degrees of freedom in T-Coupling group POPC is 33353.66
Number of degrees of freedom in T-Coupling group Water_and_ions is 53973.00
Largest charge group radii for Van der Waals: 0.299, 0.299 nm
Largest charge group radii for Coulomb:       0.299, 0.299 nm

NOTE 4 [file md.mdp]:
   The sum of the two largest charge group radii (0.597592) is larger than
   rlist (1.000000) - rvdw (1.200000)
