Loop Modeling

I ran the tutorial placed in demos/tutorials/GeneralizedKIC/exercise1/ and successfully produced 10 output structures. However, the residue ALA32 that was encompassed by the genkic mover has unwanted HN - CA bond and HN_CB bond. All the 10 output structures have this problem, and I've attached three of them. I tried to FastRelax the strucutre after genkic mover, but the unwanted bonds were still kept.

Hi all, 

I am new to Rosetta and using various Rosetta protocols, primarily remodel and pmutscan, to assess the impact of various mutations on protein stability. I would like to model the protein and associated mutations at acidic pH as this may affect salt bridge formation and overall REU score.

Hello,

I am trying to use the LoopModelerMover to relax a couple of loops in a protein complex. I would like to let Rosetta select cutpoints automatically so I leave the cutpoints set to 0. An example script is attached as a text file. I have tried specifying the loops as loop subtags and as a loops file, and in both cases I get this error. 

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

Dear Rosetta Users, 

I would like to build a linker that connects the VH to the VL domain of a single-chain Fv.
The length of the linker is ~15 aa (actually I'm going to build two linkers which differs in term of length).

In the literature, I found a case in which the RosettaRemodel application was used to perform a loop closure with a glycine-serine linker between two domains.

However, the sequence of my linker is known and it must not be changed. 
I just need to build -and not design- the linker.
