Hello,

I am receiving the following XML validation error when implementing OptimizeMembranePositionMover: 

Error messages were:

Coupled Moves crash with Membrane Protein - residue_edge is undefined for root vertex

Hi All,

I came across the Coupled Moves protocol recently and it sounds like an interesting alternative to FastDesign that I've been predominantly using. I tried to implement the CoupledMoves Mover within my RosettaScripts design script, however, I keep coming across the following error:

ERROR: FoldTree:: residue_edge is undefined for root vertex

Building loop extensions in a membrane protein with Remodel

Hi All,

I was wondering whether Remodel is currently compatible with the RosettaMP framework? I have a designed membrane protein and I'm trying to alter the sequence of water-exposed loops, which involves a few insertions. I'm using Remodel to do this but haven't been able to run it using the franklin2019 scorefunction.

Here are the flags that I'm using:

Hi All,

I am running some flexible backbone design on a transmembrane four-helix bundle heme protein via RosettaScripts. I'm finding that the membrane residue is moving a lot during design, and I have to optimize the embedding with mp_transform post-design to reposition the mem residue. I have a few questions about this:

Transmembrane helix fold-and-dock?

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?

alignblast.pl truncated file

Hi all,

I'm a bit of a novice when it comes to programming with only basic training so this problem seems to be a little over my head.

        So I know this issue has been addressed before with run_lips4.pl but the resulting solutions for that seem to be either an improper name creation or a blank blast file due to incorrect blast database downloads. While my error seems to be specific to alignblast.pl.

I run run_lips4.pl with the following command:

Changing the membrane Thickness (THKN)

Category: 
Membrane

Hello (Py)Rosetta community

Currently whenever I add a membrane to my pose the membrane thickness is always 15 A (30 total). I would like to elongate that in order to model different types of phospholipids found in bacterial cells.

My best idea to do this is to change the x-coordinate of the membrane residue in the pose object, using the following commands

>>> AID = AtomID(1, pose.size())

>>> pose.set_xyz(AID, XYZ(30,0,0))
