What is virtual atom means in a params file and how to generate it?

Category: 
Compilation

Greetings,

        I'm learning Rosetta now, when I browse the files, I find that Rosetta's database stores some params files, like 1.3.5_trisbromomethylbenzene_symm.params (in /Rosetta/main/database/chemical/residue_type_sets/fa_standard/residue_types/crosslinker), it contains several V* atoms, and I have trouble understanding the meaning of it. There is also a non-symmetric version of it, named 1.3.5_trisbromomethylbenzene.params, but it still contains virtual atoms.

Save silent results to individual directory by process ID

Docking

Hi all,

I'm running the docking_protocol application by mpirun, and I want to save silent results to individual directories determined by process ID. 

I found the option "-out:path:mpi_rank_dir" may be helpful but it didn't work. How do I use this option properly?

Dear researchers,

Those who really want to use the get_fasta_from_pdb.py script to generate the FASTA files from PDB, generally face some sorts of errors.

The most common error is: TabError: inconsistent use of tabs and spaces in indentation

Ensemble Docking with RosettaDock 4.0 Protocol

Category: 
Docking

Greetings,

I'm trying to perform an Ensemble Docking using RosettaDock 4.0 as the protocol. The structures were relaxed, and ensembles generated for both proteins. Once the runs start using the MPI version:

$ mpirun -np 24 --hostfile $PBS_NODEFILE docking_protocol.mpi.linuxgccrelease -in:file:s ../input/4udt_AB_prepack.pdb -in:file:native ../input/4udt_xtal.pdb -unboundrot ../input/4UDT_AB_renum_noHET.pdb -nstruct 5000 -ensemble1 ensemble/4udt_A_ensemblelist -ensemble2 ensemble/4udt_B_ensemblelist -partners A_B @dock_ensemble_flags

errors about RIFdocking

Category: 
Design

Hello, everyone I prepared paper_interface_design_pilot_commands. List when I did RIFdocking step 12 Running a pilot job. An error occurs when I run the command: Signal 6 (SIGABRT) means that the process was aborted.  This usually means an internal Rosetta error caused by (often)  bad inputs, (sometimes) developer error, or (rarely) hardware problems.
Has anyone encountered this error with Rosetta? How can I solve this problem? I'd be grateful if you could give me any help.

Ligand docking score.sc file containing more structures than produced

Category: 
Docking

Hello,

I was performing various ligand docking procedures using Rosie and when I was analyzing the data I noticed that some decoys had multiple entries in the score file with different scores but the same decoy model name. Is this normal and if so how can I interpret it?

For example one of my procedures created 200 docking models but the score file had 204 entries, 4 of which referenced already referenced models.

Thank you!

De Novo backbone generation vs Rosetta Match for enzdes and ligand binding.

Howdy Yall, 

So I have not been in the Rosetta world for very long, and most of what I have learned I have had to parse from the Rosetta Commons Demos/Documenation and various publications since no one else at my institution does this sort of work. So while I have learned quite a bit, there is some fundamental questions about approach/methodology that I feel blind towards.
