Dear all,

I am trying to refine in water a CYANA calculated protein-ligand structure. 

For this I would need to generate a protein-ligand complex.pdb and complex.mtf files.

Therefore, I generated the ligand topologies (.top) and parameters (.param) with LigParGen.

I added the topologies at the end of topallhdg5.4.pro, and the parameters at the end of parallhg5.4.pro.

Of course, I took care of defining the name of my residue (residue JO2) prior to the topology entries, and I close it with a "end" command. Exactly the same as for the other residues that were already in the file.

Then, I use the Recoord scripts, and I run generate.sh. 

However, the ERROR_generate tells me that the residue JO2 is not defined. When I open the generate.out I do not  see the lines for the topologies of my new residue.

Does anybody have experience with the generation of CNS compatible protein-ligand structures?

Best regards,

Felix
