Relevant number of cycles of loop closure required

Category:

Loop Modeling

Dear All,

I have been working on the Domain insertion module of Rosetta. I need to know what are the relevant number of cycles of loop closure I require to enter for larger domain sets. The domain Im inserting is around 175 aa long. I am having trouble launching the same using MPI in parallel, hence the single processor is taking days for the output. Wondered if anyone who has worked on it could suggest a feasible number for AnchoredPDBcretator and also for AnchoredDesign.

Vasavi.

GenericMonteCarloMover accept/reject moves

Category: 
Design

Hello People,

I have setup a generic montecarlo mover with backrub, but I do not get any accepted nor rejected moves, the following is my code:

backrub = pyrosetta.rosetta.protocols.backrub.BackrubMover()
backrub.pivot_residues(pose)

GMC = pyrosetta.rosetta.protocols.monte_carlo.GenericMonteCarloMover()
GMC.set_mover(backrub)
GMC.set_scorefxn(scorefxn)
GMC.set_maxtrials(500)
GMC.set_temperature(1.0)
GMC.set_preapply(False)
GMC.set_recover_low(True)
GMC.apply(pose)

RosettaDesign Result Evaluation

Category: 
Design

Hello everyone,

I wrote a script to perform RosettaDesign (both fixbb and flxbb) and I benchmarked it. Attached is the Abinitio folding simulation of three proteins, and my full script can be found here: https://github.com/sarisabban/RosettaDesign/blob/master/RosettaDesign.py

RosettaDesign improvements

Hello everyone,

 

I wrote a forum entry here (https://www.rosettacommons.org/node/10258) asking about details on RosettaDesign, and I am continuing the conversation here since I ran my script on several structures and got different results and I want a better understanding.

 

Please find attached a summery of the results. If you look closely you can see the green relaxed structure on the bottom left (sorry if it is not clear).

Hello!

 

I am using the standalone version of Rosetta, and so do for the Fragment picker application. in the tutorial, 3 SS prediction programs are used with weightage  of 0.6 for psipred and 0.2 each for other two programs; however, the Robetta server, produce results based on only 02 programs, i.e. psipred an Jufo so in this case, what is the weightage for both programs?

Thanks!

restrict PackRotamersMover

Category: 
Design

Hello Everybody,

I'm using Rosetta to find a sequence that fits a given main chain using the fixBB or the PackRotamersMover. What I haven't been able to find out: How do I tell Rosetta to use the amino acid, which was selected by the alorithm for position X, also at position X+Y? In other words, the sequence should be identical at positions X and X+Y, but I would like to leave it to Rosetta to select a suitable residue and find suitable rotamers.

Thanks for your help.

Issue with Loop Analyzer Mover ouput

Category: 
Design

Dear Rosetta Users,

I am trying to design a loop present in a protein-protein interface. At the end of my design protocol, I inserted a LoopAnalyzerMover to assess the output decoys. To my dismay, I find very high LAM score, for all loop designs. An example LAM output is below:

DDG_monomer ΔΔG question

Category: 
Design

I read the  paper Role of conformational sampling in computing mutation-induced changes in protein structure and stability (Kellogg etal.2011),

and  set the flags as row 3 , 13 and 16, and some questions comfuses me.

The paper shows  the predicted ΔΔG of row 3 is the mean of the mutant energies subtracted by the mean of the wildtype energies.

while that of row 13 and row 16 are defined as the difference between the mutant and wildtype mean of the lowest 3 energy models out of 50.
