The HADDOCK category is meant to discuss any HADDOCK-related issue. For general information about HADDOCK refer to [HADDOCK – Bonvin Lab](http://www.bonvinlab.org/software/haddock2.4) . I am not able to find and option on this server to upload the topology and the parameter files. It would be really helpful if anyone could let me know on how I could proceed with the same.

Not possible.

The server will generate automatically topo/param files for small ligands.
