Hello Ben thank you for your kind update:).

No I have taken this into account i.e. starting residue is 2 accordingly my starting missing residue is 89 so I made it 88.

Please let me know at least then which of the above I should be using for an oligomer meaning should i designate each chain?
(I will take care of the rest of the analysis to manage your time.)

Thanks Ben:)

This will just refine the loop in the A chain.

You are probably assuming that Modeller numbers the residues in each
chain starting from 1. It doesn't by default, although you can ask it to
do so:
