[gmx-users] how to solve the warning

[Jinyao Wang]

hi,gmx-user

   I make a molecule *.itp and force field parameters. When I run editconf and genbox to build a system,there are always a warning like this.
	"Warning: masses will be determined based on residue and atom names, 
this can deviate from the real mass of the atom type."
   
  I don't know how to solve the problem.
