Rosetta Antibody

Category: 
Structure prediction

Hi friends,

I want to modeling my antibody by webserver of rosetta antiboy, but I faced with the error:

ERROR: Current DB does not cover the length of FRL of your query.
ERROR: FRL length of your query: 59
ERROR: DB: 58 or 60

Would you help me to solve the error?

Remodel introduces clashes when stitching

Category: 
Structure prediction

Hi all,

So I have been trying to stitch homology models together using Remodel and when it stitches the stitched piece often ends up clashing with the structure it is stitched onto. I am using the following command:

remodel.linuxgccrelease -s model3.pdb  -remodel:domainFusion:insert_segment_from_pdb model4.pdb -remodel:blueprint model3.blueprint -use_input_sc -save_top 1 -overwrite -out:file:scorefile model3.sc -run:chain A >> model3.out

Creating FeatureReporters in PyRosetta

PyRosetta

Hi,

I'm trying to implement FeatureReporters in PyRosetta (compiled from release 3.5). I'm implementing the following methods:

  • write_schema_to_db
  • report_features

Both of these methods get utility::sql_database::sessionOP as input. When I try to run the code I get the following error message:

chothia numbering error of FR_L1

Category: 
ROSIE

I submitted a Heavy and lIght chain sequence with and without the 'multiple template grafting' and H3 loop modeling and recived the same errors each time- "Chothia numbering of FR_L1".

Does anyone know how to get around this error so that the antibody will be modeled? job #'s 24670, 24671

 

thank you

Question about homology modelling

Category: 
Structure prediction

Hello, everyone!

I have maybe quite a silly question.  What is the best methodic of homology modeling when my template and target have quite different lengths. Like target has 350 and the second has 260. Shall I just get rid of some tail part of longer protein during alignment? And yes, it seems that this is the best homolog for my type of protein.

Difficulties with Protein Docking using Harmonic Restraints

Category: 
Docking

Hello Everyone,

While trying to use harmonic, or guassian, distance restaints in low resolution centroid only docking in the docking_protocol.linuxgccrelease I've encountered weird Scoretype: atom_pair_constraint score errors that prevent the output of docked proteins.

modeling an extracellular loop of a transmembrane protein

Category: 
Loop Modeling

Dear all,

I built a model for a membrane protein and know I try to refine a long extracellular loop using NG-KIC modeling. I noticed that some sgments can reach the outer transmembrane space. I am trying now to use constraints to penalize this behaviour. In your opinion what is the best type of constraints I can use to achieve this.

"Illegal Instruction" for particular Movers/Filters

Category: 
Design

Hi everyone,

I'm attempting to use a script involving a number of different components, but have run into a certain issue.

When I intiate the mover using the attached XML file "design.txt" (which is renamed design.xml when running the script), I get an error of:

protocols.rosetta_scripts.ParsedProtocol: =======================BEGIN MOVER PackRotamersMover - pack=======================
Illegal instruction

The full log is attached (designerr.log).
