Has anyone implemented the Katchalsi katzir docking algorithm

Question

[bushranazir.333]

I am trying to implement Katchalsi-katzir’s docking algorithm in python. However I face difficulties. I want to know the following:

1. Has anyone implemented Katchalsi-katzir’s docking algorithm in python?
2. The algorithm involves rotating the ligand throughout the surface of protein and then deriving the coordinates for the maximum correlation value. Are we supposed to apply this coordinates obtained from correlation value to the rotating molecule as a translation vector?
3. Applying step 2 , separates the two molecules even more. 4 Can anyone help me with the logic?
