Loop modeling with constraints

Category: 
Loop Modeling
Constraints

Hi,

I am trying to model a loop with a constraints file (the constraints are for the atoms of the loop).

but every time I get this message:

[FILE]: src/core/pose/util.cc
[LINE]: 704
[START_MESSAGE]
Atom 'OVL1 31' not found

[END_MESSAGE]
[END_CRASH_REPORT]

 

I also tried to set the flag "-constraints:named" to true but it didn't help...

I am using the following command:

small molecule charge generated by molfile_to_params.py

Hello,

I am performing Rosetta Ligand docking for a ligand, let 's say A . The ligand A is in contact with both water and water vapor. I have two main quesions and I would really appreciate your help in this regard:

1. Do I need to explicity consider water in my docking as a separate ligand with the ligand A? Or is the implicit solvation in scoring function sufficient?

Docking

Hello, 

I am facing trouble running the script ligand interface.py. I have prepared the pdb file and params file as instructed. I have also added the params file to the default directory and updated residue_types.txt file. The following error gets invoked. Please do help rectify the error.

Hi everyone,

I would like to create some double mutations in my protein and thought to get a prediction of the ddG change using Rosetta's ddg_monomer application. I tried running the preminimization using:

Dear All,

Based on "https://www.phenix-online.org/documentation/reference/rosetta_install.html" I have installed the recent rosetta_src_2020.08.61146_bundle, and I have included "export PHENIX_ROSETTA_PATH=/your-path-to-rosetta-here/" in my .bashrc and have it sourced, with"/your-path-to-rosetta-here/" as the directory containing "demos   main    tools".

Recommendations for CoupledMoves enzyme redesign

Category: 
Enzyme Design

I'm preparing to start an enzyme redesign project using Rosetta, but the paper I'm supposed to be working off used the older enzdes application, which doesn't seem to be compatible with newer scorefunctions and sampling methods. CoupledMoves seems preferable, and I was hoping to get some recommendations for putting together a ligand docking and design protocol. I have basic familiarity with Rosetta, but since I'm the only person in my lab using it right now, I'd really appreciate any advice to help speed up the process and reduce time spent on trial and error.
