Denovo density excess map input and segmentation

Category: 
Structure prediction

I'm doing denovo density prediction. I wonder if the denovo_density can handle the presence of extra densities or the absence of denisties in the map? Would it try to fit the structure in all of the densities provided or just the relevant density? Does it undo wrongly placed fragments in more advanced iterations? 

Thanks.

Question about CartesianMD

Category: 
Structure prediction

Hi,

I am using Rosetta 3.8 and trying to use the CartesianMD mover in a RosettaScript. This is what I put in the MOVERS section:

<CartesianMD name="md1test" scorefxn="talaris2014" rattle="true" scorefxn_obj="talaris2014" nstep="1000" temp="300" premin="50" postmin="200" report="20" report_scorecomp="1" selectmode="minobj"  /> 

And after running with some general input options it gave me this error message: 

Error: Element 'CartesianMD', attribute 'scorefxn': The attribute 'scorefxn' is not allowed.

Refinement of a PDB structure containing multiple models

Category: 
Structure prediction

I'm trying to refine a multimer of alpha-beta tubulin structures. I fitted the structures individually in Chimera and saved it as a single file containing all my alpha-beta tubulin monomers. The structure saved this way contain the alternating A and B chains of the different tubulin units (ABABAB).  The refined structures, however, has only two chains A then followed by B. The A chain is the alpha-tubulin chains of all the tubulin units combined, and the B chain is also all the B chains combined (AB, where A = AAAA, and B= BBB).

Multiprocessing and running jobs on server using slurm

PyRosetta

I have a question regarding parallelizing some of the bash scripts from the refinement and denovo prediction tutorials. They usually rely on GNU parallel to run across many cores, substituting some variable in the script with a number from the GNU parallel run command . I wonder how I can run the same scripts on a server running slurm workload manager, or any other possible multiprocessing strategy using Python.

Abinitio isolated

Category: 
Structure prediction

Hello community,

 

I have found that I am using Rosetta (C++) only to run Abinitio folding simulations.

Is it possible to isolate just the Abinitio executable from the Rosetta bundle and compile it on its own, rather than keep moving and compiling the entire Rosetta (C++) software?

Running a ReportFSC mover between two .mrc maps

Category: 
Structure prediction

I'm trying to run a ReportFSC mover between two maps to debug some issue in my structure refinement protocol (https://www.rosettacommons.org/node/10195). I'm fairly new to Rosetta scripting, below you can find my attempt. What am I doing wrong? Thanks in advance.

Structure refinement guided by Cryo-EM density maps

Structure prediction

I have a few questions regarding this tutorial here:

https://www.rosettacommons.org/demos/latest/public/electron_density_structure_refinement/structure_refinement

 

1) What does ReportFSC do exactly? Does it generate a density map from the atomic model and correlates it to the test map?
