Don't. Use the one for the force field you are targetting. pdb2gmx generated the right invocation - all you should have to do is use that by generating correctly-named ions.

moleculetype CU1 is redefined<br />is it some thing wrong?</div></blockquote><br /></div>ions.itp defines molecule types for ions. Molecule types cannot be redefined. When you #included ions.itp GROMACS thought you were doing illegal redefinitions. Look back in the .top to find the original definitions, and then take suitable action.<br />
