Hello,
I am trying to use Remodel for N-terminal extension of my homotetramer. I am passing in a single subunit (chain A) and symmetry file (4 subunits identified) with my blueprint with the extra residues of interest. I am getting the following error:
File: src/protocols/loops/loops_main.cc:253
[ ERROR ] UtilityExitException
ERROR: Can’t build a fold tree from a loop with an unspecified cut point.
From the log, it looks like fragments were successfully created for the N-terminal extension. What should I try to troubleshoot?
Thank you for your help.
