Loop Modeling

Hi all,

      We downloaded Complex of a camelid single-domain vhh antibody 2P43, used Discovery Studio to change  the numbering scheme of the PDB file to  Chothia, then when we want to used "antibody_numbering_converter" to  change the numbering scheme of the PDB file from Chothia to AHo, an error occurred,  the command we used is " antibody_numbering_converter.linuxgccrelease -s 2P43_clo.pdb -camelid true -input_ab_scheme Chothia -output_ab_scheme AHo ",  the error is as follow:

I am attempting to update my group's GPCR loop modeling protocol to utilize the LoopModeler mover (rather than using the unmaintained LoopRelaxMover as we have been) and am running into errors regarding loop cut points. My XML file is as follows:

I'm trying to model 4 loops within each of 4 chains within one PDB file. Modelling the loops simultaneously is important because all chains (and also 4 another without any loops to model but interacting with that 4 remodelled) are assembled into oligomer, so that loop formation should take into account other chains. I have:

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:

[ ERROR ] UtilityExitException
ERROR: Can't build a fold tree from a loop with an unspecified cut point.
