Unsolved

The problem hasn't been solved

can't find standard or standard.wts in weights folder (?)

Category: 
Scoring

Mac OS 10.7, 64 bit (i7 processor)
Python version 2.75 (version 3.4.1 also installed)

Hey, new to both PyRosetta, Python, and molecular modeling in general, but I found the PyRosetta User's Guide and have been working through it-until I ran into an issue with the scoring functions.

It seems that the software cannot find the standard or the standard.wts file in the weights folder which is supposed to be used for creating scoring functions. Specifically, when I try the following sequence of commands:

-In [23]: name='standard'

using Rosetta to compute pH dependent binding?

Category: 
Scoring

We are interested in creating a protein that will bind to a hormone at physiological pH, but unbind to the hormone at acidic pH, encountered when the complex is cycled through the cell. To do this, we would like to use the pH_mode functionality developed by Kilambi and Gray (Biophys Journal 103:587-595, 2012).

segfault in membrane_abinitio2.mpi

Category: 
Compilation

I am getting a segmentation fault when running membrane_abinitio2.mpi with more than 2 processes. The segfault happens on line 161 in JobDistributors.cc when
job_recieved is false. Moving the statement into the preceding if block solves the problem. The patch is attached.

Cheers,
Martin

no template pdb provided for alignment

Structure prediction

Dear rosetta user:
I have try to learn the tutorial in electron_density/cryo_em tutorial /scenario2_close_homology/, but when I run the run2_relax_cm_inputs.sh, there is no output, and only a warning messege, say "protocols.comparative_modeling.ThreadingJobInputter: Warning: no template pdb provided for alignment ". Can any one tell me how to solve this problem, thanks a lot. The content in run2_relax_cm_inputs.sh is show as follow, and I have a file 1OJ8A.pdb in the fold.

ddG_monomer

Category: 
Structure prediction

I am trying to use ddG_monomer in Rosetta 3.5 to examine the structural effects of a single point mutation. Based on experimental data, it appears as if the mutation causes changes to the backbone of the structure. I would like to use the Monte Carlo ensemble method (protocol 20) from Kellogg et al. paper to model these changes but have not been able to locate the ensemble_generator_score12_sidechain_ver2.linuxgccrelease application listed in the supplementary methods section of the paper. Is the backrub application equivalent to ensemble_generator the application?

Enabling N-Linked Glycans

PyRosetta

Hello,

I am currently trying to analyze a crystal structure that has various N-linked Glycans attached and would like to be able to work with these glycans in PyRosetta. However, if I try to work with the structure without cleaning it I receive the error message:

>>>pose = pose_from_pdb("my_molecule.pdb")
core.chemical.ResidueTypeSet: Finished initializing fa_standard residue type set. Created 9172 residue types

Problems with fixbb in Rosetta 3.5

Category: 
Design

Hello,

I am trying to run fixbb on a heterodimeric protein and explore different residues at 2 different positions in one chain. The program runs without error however all the structures output (100) have the native residues at those 2 positions. My .resfile and flags are below.

Resfile:

NATRO
EX 1 EX 2
USE_INPUT_SC
START
72 A NOTAA C
79 A NOTAA C
