Hi! @tomhennigan

https://github.com/HommaF/AlphaFold2_chapter/issues/1

Just responded in the linked repo where you raised the question originally.

I think the issue was that when modeling a protease-inhibitor complex, you hadn't removed the prodomain of the protease. I assume you will be able to see the prodomain occupying the binding groove in the output PDB files. Let me know if the complex between the mature protease (Pip1) and the inhibitor (EpiC2B) gave higher scores. For more details and the sequences, see the linked repo.

Thank you very much! @FelixHomma After removing the prodomain of the protease, I got stable iptm+ptm values.
