I have a subunit of homodimeric protein, and I want to build a dimer, so I used the Easy interface that gave me acceptable results. my question is this method correct or do I need to choose the Guru interface?
If you are looking at a symmetrical homodimer, you might want to use the C2 + NCS symmetry option (guru interface).
Check for some hints our tutorial about about a symmetrical homotetramer docking at:
Thanks for useful tutorial, but I got this error
HaddockValidationError: You must supply active and/or passive residues for your first protein.
What are exactly the restraints you used for your docking run? You must specify:
center of mass--> TRUE
Noncrystallographic symmetry--> TRUE and use the menu to define one pair A-B
C2 symmetry segment pair--> TRUE and use the menu to define one pair A-B
That should do the trick
