BioExcel and WestLife have supported the work on a complete new design (and machinery) of the HADDOCK portal. The new version (HADDOCK2.4) does support cryo-EM data and will allow multibody docking up to 20 molecules!
Description of its implementation is available in Zenodo (DOI:10.5281/zenodo.1252961) as a WestLife project deliverable.
We will soon be looking for beta testers to get feedback before putting it in production mode. So if you are interested, do contact us at software.csb_at_bonvinlab.org.
