Abinito for Multimers

Submitted by Prasanth Kumar on Wed, 2014-01-22 17:45

Dear friends,

I am new to rosetta, so can someone help me to figure out how to do ab-initio for a subunit in a multimeric protein.

I am interested in doing ab-initio for one subunit whose crystal structure is not known and the crystal structures of other non-covalently interacting subunits are completely known. It is experimentally known that the subunit whose crystal structure is not known is predominantly helix and also the approximate position of the helix is also known.

Please help me!!!

rosetta's keyword list

Submitted by fred on Tue, 2014-01-21 06:03

Hi there,
Is there a Rosetta keyword list somewhere? There are some keywords that cannot be found issuing the command option "-help".
To be more specific, there aren't neither the keywords constant_seed nor jran in minirosetta -help. I also could not found these keywords in the online manual. Thanks in advance.

is_aromatic function

Submitted by jadolfbr on Mon, 2013-12-02 19:31

Hey All,

This is probably something stupid, but I'm trying to use the is_aromatic function of Residue via python and c++ and everything returns false in a few different poses where aromatics are present.

for i in range(1, p.total_residue()+1):
print p.residue(i).name3() +" "+repr(p.residue(i).is_surface())

I have checked the params files of some aromatic side chains to make sure it is listed in the properties line, and that seems to be fine.

Am I missing some nessessary call to another function?

Score - Strange message

Submitted by Ashafix on Wed, 2013-11-20 15:23

When I was trying to rescore and combine a list of PDB files which were created by loop modeling with the score application I get the following message:
hey is this the right thing to be doing???

It seems that the silent file is OK, as well as the score file. Does this message mean anything?
Google wasn't very helpful, only a BOINC/Rosetta@home user with the same message.

The command I was using:

change dihedral angles of any residue

Submitted by bharat_46010 on Fri, 2013-11-15 00:30

Hi,

I am interested in changing the psi-psi angles of two residues in a turn. When I use set_phi/set_psi command to change the angles, it completely disrupts the structure. Is there any way to only change the dihedral of those two residues alone without changing/disrupting the structure. I tried the same thing in Pymol, but there also I get the same disrupted structure. Can anybody suggest some other tool ??

Is it wrong to change dihedral angles of certain region and freeze the other regions of protein ??

Pls reply..............

Documentation of ``mysterious'' protocols

Submitted by ñ on Wed, 2013-10-30 08:19

Hello,

I've been using PyRosetta's pre-packed protocols like ClassicRelax, FastRelax and LoopMover_Refine_CCD thoroughly, but I've been unable to find documentation of these. I would like to know which steps are taken by these protocols in order to complete their tasks; if such information is available, could someone link me to it?

In Workshop #5: PyRosetta Refinement, it is pointed that ClassicRelax is the standard Rosetta refinement protocol, similar to this one (http://www.sciencemag.org/content/309/5742/1868.long); finding a paper describing the other protocols would be very nice.

Cannot confirm registration to the Rosie site

Submitted by fglaser on Sun, 2013-10-13 02:52

I solved it, I think there was a cookies problem...

Thanks anyway,

Fabian

=====================

Dear all,

I registered to Rosie web site, which sent to my email a confirmation link. This link though produces an error message instead a confirmation.

Error 500

We're sorry but we weren't able to process this request.

Can you please help me to complete the registration so I can use ROSIE?

I tried with two different users names: fglaser and fglaser_rosie, and with different emails fabian.glaser@gmail.com and fglaser@technion.ac.il, nothing worked....

MPI stall

Submitted by jadolfbr on Thu, 2013-10-10 18:59

Hi all,

Has anyone ever had any problems with the master MPI process stalling as it's cleaning up / giving more work to a slave or a little afterward?

I am running more tests tomorrow, but I have had it stall (While still saying it at 100 % cpu) with its output garbled like this before it just stops communicating with the rest the slaves. Once it stops communicating, all the slaves continue to run, but nothing gets output and the job needs to be cancelled. Also, no error message is reported from MPI or Rosetta. It just silently stops:
