RosettaCM: help to generate similar models as those from Robetta Server

Category: 
Structure prediction

Hello,

I have a query protein with 300 amino acids and I want to predict its homology models based on the template (saying templateA.pdb) with exactly same 300 amino acids (for testing purpose).

By using Robetta Server, what I did was listed below:

I pasted the query target sequence, and I selected comparative modelling option and set 1000 models.

I then uploaded the template PDB structure (templateA.pdb).

running Rosetta with MPI

Category: 
Compilation

Hello,

I am planning to do four different docking (with 200  structures for one of the partner to capture backbone flexibility) with at least nstruct=500. I need to run it by usening several nodes and processors in our cluster.  I tried to compile MPI  in our cluster, but I got an error attached to this post. Could you please guide me how I can solve the error?

multi state protein design

Category: 
Design

Hello,

I have an enzyme and I want to optimize its sequence to increase its binding to one protein and decrease its binding to another protein at the same time. I recently attended Rosetta workshop and learn about multi state protein design which can be used to increase affinity of an antibody to its ensemble of antigen, but I am not sure whethe it is applicable to my case. I would appreciate any suggestions.

Number of max allowed mutations from WT sequence

Category: 
Design

Hi folks,

I wonder if there is a way to constrain the number of maximal allowed mutations from the input sequence when doing a regular backbone-fixed design or a backbone-flexible design. For example, I only want the designed sequences away from the wild-type sequence by 5 residues at most (i.e. including 5, 4, 3, 2, and 1 mutations). Many thanks!

How RosettaCM can perform part of C terminal domain (CTD) structure prediction without proper template structures (coordinates)

Category: 
Structure prediction

Hello,

I want to know in RosettaCM (or Robetta Server), how to generate the C terminal domain (CTD) coordinates where this query CTD domain has no corresponding template structures?

Here is the example:

Extracting top score PIPER models

Category: 
Docking

Hello,

I am docking a peptide in a receptor with PIPER using the steps in https://www.rosettacommons.org/docs/latest/application_documentation/docking/flex-pep-dock.

The step 2.III of the PIPER-FlexPepDock protocol uses the apply_ftresult.py script which is not present in the source. Where can I get this script or an equivalent?

RosettaCM: adding constraints while keeping AUTO constraints

Category: 
Structure prediction

Hi all,

I am working on the structural prediction of a symmetric multidomain protein using RosettaCM - I have to add a tetramerization domain for which no template structure is available, but for which I can set some distance constraints to steer the prediction in the right direction. For this, I changed
