Mutate residue with NCAA

Category: 
PyRosetta

Hello,

I am trying to mutate a pose with beta-amino acid residues. From what I've tried and read, it's impossible with both mutate_residue and MutateResidue mover, because they only take one letter representations of the residues. My hope is that I can figure out how to do it through packing. I'm not sure how to make it work properly.

This was just my test code to see what would work:


pose = pose_from_sequence('A'*20)
test_pose = Pose()
test_pose.assign(pose)

mutant_position = 3

Structure not changing after pose.set_phi

PyRosetta

Hi, I am trying to implement the Generalized Simulated Annealing routine (Tsalis et al, 1996) and apply it on folding processes.

To do so, I code the mover w.r.t. dihedral angles (each step phi and psi sufer a small, guided perturbation). I am using the pose.set_phi and .set_psi methods to modify pose coordinates. 

The problem:

I am trying to use IntearctiveRosetta on windows 10 environment and have zero knowledge about coding.....could anyone help me to solve this error......which comes up when I do a position scan using IntearctiveRosetta.....

PyMOL not displaying mover input

Hey there.

I run a Linux subsystem (Linux 4.19.128-microsoft-standard x86_64) on Win10 (Build 19041.508) with wsl2 and Ubuntu 20.04.1 LTS. I successfully installed PyRosetta 4 (python 3.8 release 265).
Python: 3.8.2

On my windows I installed Pymol 2.4.1 198.

If I tell PyMOL to execute the PyMOL-RosettaServer.python3.py script from PyRosetta folder,
-> run \\wsl$\Ubuntu-20.04\home\[User]\PyRosetta4\PyMOL-RosettaServer.python3.py

"Server Could Not Be Reached" although I have an Internet connection

Category: 
PyRosetta

I am a new user of Interactive Rosetta, I use the software as guided in the tutorial. But when I want to "Thread" my protein, it came up with the message "Server Could Not Be Reached". I have already tried with several different Internet connection, but it still came up with this message. May I know how can I solve this problem? Thank you! 

 

Description of the message: 

The comparative modeling job could not sent to the server! Verify that you have an Internet connection and that the server is running.

trRosetta modelling with a ligand

Category: 
PyRosetta

Hi all,

 

I am trying to modify the trRosetta scripts to run it with a ligand (heme; I added few distance constraints between the protein residues and atoms in the ligand).

I ran molfile2params with the -c flag and have both centroid and full atom params and pdb files of the ligand. I inserted the ligand to the pose and converted it to centroid mode for the initial folding calculations. When I add my ligand constraints prior to the minimization stage, after all the network constraints are read, I get the following error:

Calling SnugDock from PyRosetta

I am very new to the PyRosetta platform and was hoping to get some guidance on how I can do a SnugDock run from the PyRosetta interface with an antibody pdb and antigen pdb, as I know that the ROSIE queue can be quite long. I've seen the PyRosetta 4.0 documentation for SnugDock but am a little bit overwhelmed as I'm not too well versed in Python. Any level of guidance would be greatly appreciated!
