yes where iii has many variants.

Yes coordinates will change and so they are poses according to my
However, and most importantly, the control of those poses is completely
independent of DOCK's sampling algorithms. So for example, none of the uses
of scoring in anchor and grow can be performed with Amber score:

In DOCK rescoring is synonymous with secondary scoring.
And note that again Amber score is odd since it cannot be directly
specified as a secondary score:
One technical problem with the Amber score implementation causes all
these limitations, and correcting it is on the todo list.
