Scripts and/or strategies for saturation mutagenesis simulations?

Category: 
Scoring

Just wanted to confirm there is no semi-official script or protocol for DMS using Rosetta and ddg cartesian? 

Seems like an easy enough thing to script using existing methods and protocols....but ideally, I would like a strategy that avoided generating 19 WT models per-site, per-iteration (since just one set would suffice for all DDGs).

That would same me a lot of comput time. For a 500aa protein with 10 iterations per DDG estimate, that would save me from building (18x500x10=90,000  superfulous models.

Global Docking with output analysis RMS

Category: 
Scoring

Hello, Rosetta team

I performed global docking for two proteins and got the output.sc file, there are different "RMS"s reported, Irms, Irms_leg, cen_rms, rms, and st_rmsd, what values are more useful for analysis?  I wonder if term "rms" is calcualted based on what? since I started with two far away proteins for global docking, I wonder if this rms is calcualted based on the intinial structure?

I did not provide native structure for global docking.

Hello, I encountered an error while attempting to use the 'SapScoreMetric' in RosettaScript.

I encountered the following error, but when I exclude the 'SapScoreMetric' parts, it works well.

[ ERROR ]: An issue with your Rosetta run was detected

Please correct the following issue and retry:

different relaxed energy scores for one same protein structure

Category:

Hello everyone,

 

By chance, I tried several times relax module for one same protein structure.

I got all different relaxed energy socres.

Which score is representive for this protein structure?

 

And of two similar structures mutated by 1 or 2 different positions, which structure can have the better structure?

By what criteria did you think that?
