rosetta for phenix directory cannot be found error

Category: 
Phenix / MR Rosetta


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.

C-term amidation

Design

Hello,

I have been trying to use the Cterm_amidation patch, but everytime I use it in FastDesign or scoring it turns it back into a regular C terminus.

I've read the posts from other users, but I still can't make it work... What am I doing wrong?

Things I've tried so far:

I added "-include_patches Cterm_amidation" flag, both with the input file having a regular C terminus and with a neutral terminus - in this case I made sure the names of the atoms matched these in the patch:

Error from clean_pdb.py

Category: 
Structure prediction

Dear Rosetta Users,

I'm recently studying the Comparative Modeling tutorial: https://www.rosettacommons.org/demos/latest/tutorials/rosetta_cm/rosetta_cm_tutorial

When I ran the script: clean_pdb.py, there was an error: /dors/meilerlab/apps/Linux2/x86_64/bin/python2.5: bad interpreter: No such file or directory.

What can I do to fix this? The python on my computer is python 3. Thank you in advance!

Hi everybody!

I'm trying to install Rosetta (version 3.10) for use in Phenix on Ubuntu 20. No problem with Phenix installation, but when I run "rosetta.build_phenix_interface nproc=2" I got the following:

Substituting phenix.python into build shell scripts
  update_options.sh
  update_ResidueType_enum_files.sh

  Phenix modules found : /home/stefano/programmi/phenix-1.19.1-4122/modules/phenix
False

Hello all,

I am trying to model the H3 loop of a nanobody (VHH). The protocol runs fine and completes successfully but it gives a lot of the following error messages:

......
