[gmx-users] Grompp error

[Farid Sa'adedin]

Dear Users,

I have added Cl ion to my peptide in water system pdb and topology files.
But I have a problem when I run grompp:

Fatal Error: Atoms in the .top are not numbered consecutively from 1.

The pdb is numbered correctly and I have added the the spc.itp and 
clion.itp to the topology file.

Any ideas would be appreciated

Thank you in advance.
