[gmx-users] grompp error

[Triguero, Luciano O]

Hi Everybody,
 
I have been working with the topolgy file creating a new residue type to include some metal-aminoacids ligand complex.
So far, pdb2gmx provide the topology file without errors and this file seems to contain all te interaction I added in the correspondign databases. However, the grompp gives the following error message after processing the (.top) file. 
Any sugestion where to look or solve this problem?
 
Thank is advance,
 
Luciano
