Questions regarding fragmentation using Robetta

Category: 
Structure prediction

First I want to make sure that I understand this correctly. Fragmentation creates L-K+1 fragments, blasts them against some database and finds the homologous secondary structures that are shown below (small portion as an example).  Correct?

Efficient implementation of MPI with protein design programs

Category: 
Design

I'm running Rosetta single state design (though I imagine my question applies to MSD as well), which works great on a single core or my local machine.  I'm using rosetta_scripts.mpi.linuxgccrelease as my package.  It is compiled by my HPC administrator to function with the cluster.

free up space after building rosetta

Category: 
Compilation

Hi eveyone,

I built Rosetta on a linux machine and it takes up 24G of space. However, I'd like to remove extra parts (like demos or pilot apps) or in any other way, reduce this space.

Is there any solution for this? Is it possible to keep the shared libraries and .so files and remove all the codes?

Thanks a lot in advance,

Hamed

Multistate design output

Category: 
Design

Hi all,

Sorry to trouble again.

I understand that the multistate design protocol outputs structures where the chains A and B will become AA, AB and BB.

However, I get the output of chains A and B even in the output files AA and BB.

May I find out how I could produce the output files AA and BB homodimers?

Is this something to do with my corr file?

The question about ligand score function

Category: 
Small Molecules

Hello!

These are many .wts file in database\scoring\weights.
I  don't clearly know which weight is used in which occasions,
and  just use score function according to papers.


I  read the webpage(https://www.rosettacommons.org/demos/latest/tutorials/scoring/scoring)
 and its recommend references.

I'm trying to run python /home/labusr/rosetta/main/source/scripts/python/public/molfile_to_params.py --keep-names --clobber --extra_torsion_output --centroid gtp.mol2 -p GTP -n GTP, on a gtp.pdb that has been reduced using phenix.reduce and converted to mol2 using openbabel. Below is the error I get.

Multistate design on Rosetta - no generations produced

Design

Hi,

I am currently running a multistate design protocol (mpi_msd.linuxgccrelease) for bispecific antibody design. After I have run the protocol with my options, the program runs and is "stuck" at this point for a long time:

core.pack.pack_rotamers: built 39485 rotamers at 58 positions.
core.pack.interaction_graph.interaction_graph_factory: Instantiating DoubleLazyInteractionGraph
core.pack.interaction_graph.interaction_graph_factory: IG: 22325380 bytes

The question of ligand docking with constraints

Category: 
Docking

Hello,

I read the paper Rosetta and the Design of Ligand Binding Sites

and it enlightens me.

According to the method of this paper,  I design my enzyme.

However,  I find these are a few unreasonable results which show reaction atom of ligand  do not close to  catalytic triad,

but  the opposite side of ligand close to  catalytic triad.

So I want to  make docking with  constraints
