Hello, I tried to dock an inserted domain 2 to a domain 1. The domains are arranged as follows in the sequence: 111111111111222222222222221111111111111111111111 Using the easy interface, for protein 1, I specified the two adjacent residues (213, 214) as active and for the 2nd protein I specified the N- and C-termini as active (1 and 117). Unfortunately, the docking failed with the error message below ([http://milou.science.uu.nl/serviceresults/HADDOCK2.2/5538826474/PositiveContrl](http://milou.science.uu.nl/serviceresults/HADDOCK2.2/5538826474/PositiveContrl)) : TOTAL NUMBER OF DISTANCE RESTRAINTS FOR RIGID BODY DOCKING IS ZERO! CONTROL YOUR PARAMETER SETTINGS AND RESTRAINT DEFINITIONS STRUCTURE NUMBER 601 I would be grateful for any help, or info if that approach is possible or not. Many thanks Andreas ---

Could be a mystery of the grid (on which our jobs are running)… Or bad luck in some way. I restarted your run and it seems happily proceeding: [http://alcazar.science.uu.nl/serviceresults/HADDOCK2.2/1111111111/test2/](http://alcazar.science.uu.nl/serviceresults/HADDOCK2.2/1111111111/test2/)
