I am using the RosettaAntibody3 workflow outlined here:
Everything is “working” when I use the command:
antibody_H3.linuxgccrelease
-database $ROSETTA_DATABASE
-s /input/TB184-140-0.relaxed.pdb
-ex1
-ex2
-extrachi_cutoff 0
-out:file:scorefile /output/my_antibody_h3.score
-nstruct 1
and based on the documetation, I am expecting the final output to have a extended (non-kinked) H3.
However, the output of the run shows extended?: False:

Does anyone know how to force RosettaAntibody (antibody_H3.linuxgccrelease) to model a extended H3?
I have also tried adding the flag -extend_h3_before_modeling with no change.
