Protein-Protein docking with ligand

Dear Prof. Bonvin and Haddock team

Last week I ran a docking simulation for 2 proteins, one of which contains a ligand. Everything went fine and results were as expected. This week I tried to change a few parameters and run it again but I cannot get further than the file submission. I am using the same file but Haddock insists that my pdb file contains a ligand which is incompatible with the chosen mode (protein or protein-ligand). Do you have a suggestion what I am missing or doing wrong?
Thank you in advance for your time and your answer.

P.s. the format looks fine in text editor, copy and pasting it distorted it here.

Last week we changed a bit how the moleculetype field selector work.

Since you are using the same files as before, could you share the link of your previous successful run? If you prefer to send it privately, send it to haddock.support@gmail.

We have identified and fixed an issue with Protein-Ligands ensembles which probably causes your issue, please try submitting again! :slight_smile:

Thank you for the quick reply and the fast fix. It works again :slight_smile:
