Thans`s David and Patricia:
                           I check the topology very times carefully
but the error message is the same;

#define _FF_GROMOS96
#define _FF_GROMOS96A

  [defaults]
1    1    no    1.0    1.0
  ..........
  ..........
;new start the molecular definitions
  [moleculetype]
  [atoms]
  [bonds]
  [pairs]
  [angles]
  [dihedrals]
  [dihedrals]
#include "dmso.itp"
  [system]
Protein
  [molecules]
Protein      1
DMSO       3579

                     there is any way to look out how gromacs read the
topology file?. Somebody has worked out with convert
topology?
               Thank`s again.
