I am new to MPI so please correct any misuse of terms. My question is about optimizing for MPI on an HPC or a second (preferred) solution to my issue is to optimize my RAM usage so I don't have to run MPI, serial would actually improve overall models produced anyways.
I would like to run a design protocol on a protein that has, as its asymmetric unit, 2 proteins with an ion. I have done some purely AA-based symmetric design before with 2 chains controlled by separate virtual jumps and my own python-generated symdef file but I'd rather avoid doing that again :-)
My hope was that I could put (even if suboptimal) the 2 chains and the ion in a single chain and proceed as usual in symmetric design with one chain.
I'd like to do something similar to regular Rosetta fold-and-dock but in PyRosetta. I've looked at D060_Folding.py and D100_Docking.py examples and while I (mostly) understand what each is doing, I have no idea how to combine them.
How to get a foldtree with symmetry? (in my case it's just simple C3)
How to combine folding and docking? Just alternate calls to folding.apply(test_pose) and dock_prot.apply(test_pose)? (It can't be that simple...)
I'd like to fold-and-dock a trimeric transmembrane domain. I mostly have the "Fold And Dock" working following the example in demos/public/symmetry_examples/fold-and-dock/. However this is treating the transmembrane helixes as though they are in solvent (so for example any hydrophilic groups always rotate outwards). I'd like to do something which is a combination of "Membrane Abinitio" and "Fold and Dock". Is this possible, and how do I do it?
I'm folding a protein which is a trimeric long helix bundle. I started from the main/demos/public/symmetry_examples/fold-and-dock/ and added my info (sequence, fragments etc). This basically works but a lot of the resulting folds are globular not long - the helixes fold over on themselves. I'd like to constrain this to extended conformations only.
I looked at constraints in the Rosetta docs, and tried creating input_files/constraints.cst to give a penalty to any structure which has less than 50-70 A distance between residues 1 and 63:
I am trying to use Remodel for N-terminal extension of my homotetramer. I am passing in a single subunit (chain A) and symmetry file (4 subunits identified) with my blueprint with the extra residues of interest. I am getting the following error:
[ ERROR ] UtilityExitException
ERROR: Can't build a fold tree from a loop with an unspecified cut point.
I want to redesign the interface of two three-fold symmetrical proteins and I thought of using RosettaScripts.
I first wanted to make it work on one three-fold symmetrical protein and then continue with the interaction, but I am stumbling on some errors.
I'm using LinkResidues, because the protein is three-fold symmetrical, so a mutation on residue a should also occur on residue b and c, thus without breaking the symmetry of those residues.
