Docking peptides with modified amino acids

Hi,
My peptide has several N-methylated amino acids and HADDOCK fails as it cannot recognize them. Not all of my residues are included here - http://haddock.science.uu.nl/services/HADDOCK/library.html
Is there still any way to use HADDOCK to still dock the peptide? Is it possible with the expert interface? How do I register for that?
Thank you.

Unfortunately if the residues are not listed in the list of supported modified amino acids you won’t be able to use HADDOCK for this.
Topologies and parameters would have to be defined for those (and you can’t upload those to the server).

As for expert access, you can request it in your registration page.

Are we still unable to upload parameter files of modified residues (beta-Lysine in my case in a protein-nucleic acid docking) to the web portal ?
also would like to know how these parameter files are made, any tutorials on them?

No support for modified parameter files and topologies.

You would have to run a local version for that.

And we don’t have any tutorial on how to generate custom topo/param files I am afraid. Not so trivial…
