Denovo density didn't output a structure

Category: 
Structure prediction

I had a bunch of assembled fragments and I ran the below protocol on them for the fragment assignment and the genration of a consesus trajectory. 

#!/bin/sh

$ROSETTA3/source/bin/denovo_density.linuxgccrelease\
	-mode consensus \
	-in::file::silent round1/assembled.*silent \
	-consensus_frac 1.0 -energy_cut 0.05 \
	-mute core

# use the old model as a starting point
cp S_0001.pdb round1_model.pdb

Repeating sequence in Rosetta de novo protein folding

Category: 
Structure prediction

Hi,

I am trying to do a de novo protein folding from a protein sequence with repeating Gly and Arg only.

So the sequence looks like GRGRGRGRGR..... I put the sequence onto Robetta Fragment Server and it gave me this error message:

Calculate ddG in mutation scan of a homodimer

Category: 
Structure prediction

I'm new to Rosetta, and trying to figure out how to calculate the ddG of the interaction between Chain A and Chain B (which homodimerize) for all possible substitutions at each residue compared to wild-type (where Chain A and B will always carry the same mutation). Are there any existing packages that will handle this, or what script would you recommend for my situation?

ERROR: FragmentIO: could not open file

Category: 
Structure prediction

I created a fragment file of my structure using Robetta, the link to the results is right here http://robetta.bakerlab.org/fragmentqueue.jsp?id=51178. I'm using the

fragment file to do density guided structure prediction as described in the paper "De novo protein structure determination from near-atomic resolution cryo-EM maps". 

I'm trying to run the code below:

running structure prediction with robetta server like automation

Category: 
Structure prediction

Hi All

       is there any way that I can perform the structure prediction using rosetta locally the way we can do on robetta server? I was going though the protocol for comparative modeling but its quite involved. I am looking for something that provide me robetta server kind of automation.

Thank you

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

Category: 
Structure prediction

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.

Structure refinement with RDC constraint

Constraints

Hi~

I've done a structure refinement of a protein by Rosetta3.8.

However, I'm not sure that what I've done is correct or not.

The protocol that I followed are list below:

First, I put my protein sequence(.fasta file), torsion angle(predicted by talos+), RDC value(experimental data) into the website( http://robetta.bakerlab.org/fragmentsubmit.jsp) to do fragment generation.

Expanding the silent file

Category: 
Structure prediction

Hi Rosetta Community,

With comparative modeling application I created a silent file output using following flags

-out:file:silent threaded_model.out
-out:file:silent_struct_type binary

Later, when I used the generated silent file as an input for other applications like "cluster" or "score", it crashed with an error.

ERROR: Assertion `is_int( tag )` failed.
ERROR:: Exit from: src/core/io/silent/RNA_SilentStruct.cc line: 292

 

Is there any easy fix for that?
