What is the best way to install PyRosetta for use with Protein MPNN? I am installing it for myself on an hpc cluster (redhat linux 8) and haven't found much documentation outside of that for the general PyRosetta install.
Based on the NMR NOE data, I want to use PyRosetta for the structure prediction of my peptides having unnatural amino acids. I went through the manual but couldn't find much information for structure prediction based on NMR data. It would be of great help if you cite protocols, scripts or literature used to determine the structure using NMR data in PyRosetta.
I hope this message finds you well. I noticed after running FastRelax on output pdb files from AlphaFold Multimer that the pLDDT scores encoded in the B-factor fields have been altered. Is there a way to avoid this and maintain the original pLDDT scores? I have attached the code I am running below.
I need to create mutant peptides with Rosetta to use in Virtual Screening, the mutations need to be kinda ''random'' (not chosen directly by me) and, if possible, following an evolutionary bias (genetic algorithm). I'm really new at protein modelling and I have only used AlphaFold. Rosetta has many ways to use, and I'm kinda lost, should I use Rosetta Scripts or PyRosetta? Can I do this with both? I haven't found any tutorial that explains how to create mutant peptides following a genetic algorithm with rosetta :( I don't know where to start.
I need to create peptides to use them as flexible ligands in docking (DockThor platform). I'm new at pyRosetta so I've only seen 1 tutorial until now. I'm using the following code
from pyrosetta import *
from pyrosetta.toolbox import *
peptide_sequence = 'insert peptide sequence'
pose = pose_from_sequence(peptide_sequence)
scorefxn = get_fa_scorefxn()
# define variavel score before relax
score_before_relax = scorefxn(pose)
I want to relax a designed disulfide bond with FastRelax, but when I try to do it in Pyrosetta it seems like it gets no optimization at all. However, when I try FastRelax in rosetta scripts I get a good geometry. Could you please help me identify what I am missing in my Pyrosetta code?
I've been trying to trial designing antibody CDRs. Thus far I haven't had much luck applying standard methods. I've converted my antibody to AHO scheme with PyIgClassify and applied the cleanATOM method, however, I am still running into the following error prompt. Any recommendations on how to resolve this, would be great.
I've applied the AntibodyInfo method and am able to print the antibody with the sequences of each CDR, so I don't think the first portion about start and end not being contained is correct.
