Robetta server is failing to generate fragment libraries with backbone chemical shift input for the past week!. my current job is at (http://www.robetta.org/fragmentqueue.jsp?id=39986). I also observed its failing for other users as well. can you please fix the issue.
I build Rosetta 2015.12 on Scientific Linux 7 (SL-7). And, I follow the protocol of RosettaAntibody3 to do antibody modeling.
When, I run the script of “antibody.py” through following command as
I have been trying to run a theoretical alanine scan on a protein.
Unfortunately, I cannot repeat the results I obtain when I run exactly the same experiment (just copy all files to a new directory and run again) more than one time. Attached is a png of the correlation between run 1 and 2. The black line is 1:1 correlation. You can see that some mutants look ok (green ring) while others are very badly different (red rings).
I'm running the high-res protocol of the ddg_monomer on a 439 residue enzyme structure (following the the Kellogg paper and online docs protocols) and I'm seeing some odd score outputs.
There are three types of odd outputs in the ddg_predictions.out file:
Recently, I am trying to predict flexible tail region of protein by using Floppy tail.
First I tried to use Floppy tail with test data (4tailstestdata.pdb).
I have run Floppy tail as below command
mpiexec -np 4 FloppyTail.mpi.linuxgccrelease -in:file:s 4tailstestdata.pdb -in:file:movemap mapmover -nstruct 4
RESIDUE 90 117 BBCHI
RESIDUE 207 233 BBCHI
RESIDUE 324 351 BBCHI
RESIDUE 441 468 BBCHI
and I got 4 pdb files those file and each model has different amino acid sequence.
(relevant files can be downloaded at https://copy.com/yOhxRslZzK8j9z0l)
In the instructions about ddg_monomer,
it is mentioned that "the most accurate ddG is taken as the difference between the mean of the top-3-scoring wild type structures and the top-3-scoring point-mutant structures".
(I would appreciate it very much if any of my questions can be answered.)
I have been trying to reserve the disulfides of my target protein during the minirosetta comparative modelling. However, though I have gone through many posts, I still could not work it out after using several disulfide related flags.
My situation is:
in the target protein:
Light chain (LC): residue 1-214
Heavy chain (HC): residue 215-442
I am interest in, which force field Rosetta use and which energy functions are applied for a normal abinitio calculation. If I used an abinitio calculation with a metallatom, are there used a other force field for the zinc atom?!
Can anybody advice my a good paper which an easy explanation or something like that?!
