de novo RNA loop

Category: 
Nucleic Acids

Hello, 
I'm using the rosetta rna de novo tool to generate a rna hairpin, I used the RNA_Denovo_with_base_pair_steps demo as a guide to do it, however I get the error: Atom C1' 1 not found. I' m newbie using rosetta so I would really appreciate any help or guide about the problem. Thank you!

rna_denovo secstruct_general function

Category: 
Nucleic Acids

Hello all, I had a question about how to properly use the -secstruct_general flag to input non-canonical and canonical basepairing interactions. I'm trying to test this on a simple structure from the 3IRW RNA that has a non-canonical g a basepair but I keep reseiving errors.  I am running the following command with the following files.

 

rna_denovo.static.linuxgccrelease -nstruct 1 -fasta ../test.fasta -secstruct_file ../test.secstruct -secstruct_general ../test.secgen -minimize_rna true -out:file:silent testing.out

Dear Rosetta users,

I recently install Rosetta and want to work with Rna_Denovo, when I run the command line below I got this error:

Modelling temperature dependent RNA structures

Category: 
Structure prediction
Nucleic Acids

Hi to all,

I am really new to rosetta. I am using rna_denovo to generate 3D structures of RNA. I believe the default tempertaure used for modelling is 300K. I want to know if we can set our own temperature  for modelling RNA ? I did saw the option of temperature in the -help, written as 2 in the settings option, but I am not sure how to use it. Can we just define the temperature that we want, after writing this option? I am not sure how to go about this.

Please let me know the best way to go about this. And many thanks.

Rna Denovo

Category: 
Nucleic Acids

Dear all,

Im using RNA Denovo rosetta protocol to build a 3D model of a small RNA segment (~10 nucleotides). For a specific purpose, i would like to model a ensemble of this ssRNA segment avoiding base pairing. I tried to modify some parameters but the ssRNA built is always packaged, with some base pairs. Is it possible to model such ssRNA using Rna Denovo protocol? 

 

Thanks in advance for any help!

DNA-protein docking

I didn't find any contemporary comment on that so I'd like to ask about how to dock protein structure to dsDNA in Rosetta? Is that possible now anyhow?

I have small protein structural motif, like HTH and try to model its interaction with a sequence within dsDNA to get some hints about which residues will bind to which DNA bases so I don't have to scan along huge DNA strands but rather have a well-defined location within the major groove to explore.

Thanks for all advice.

FARFAR2 error

Hi ROSIE and FARFAR2 team,

       I used FARFAR2 to test the 3D structure prediction of several RNAs two weeks ago with native PDB uploaded. But all the jobs were finally dead with the error message "2-rescore_to_native_or_lowest". Could you tell me why this happened? You can find the sequence, 2D structure, and native PDB in the attachment.

Ligand question - aromatic bonds not being enforced?

Hi,

I am trying to run Local Relax on an ADP-bound protein structure. I cleared the first hurdle to make a ligand params file, and the program runs fine and includes the ligand. I made the params file by taking ADP from a related structure, converted it to mol2 using iBabel, and made the params file using molfile_to_params.py

Installing rna_denovo

Category:

Hi,

I tried using the Rosetta RNA tertiary structure modeling pipeline as described in your article "Modeling complex RNA tertiary folds with Rosetta."

My build is correct.

But every time I try to run

helix_preassemble_setup.py -secstruct sec.txt -fasta fasta.fasta

I am getting error as
