HBNetStapleInterface

Category: 
Design

Hello,

is HBNetStapleInterface avaliable in the current version of Rosetta?

In 2016_15 build i get:

Error: ERROR: Exception caught by rosetta_scripts application:HBNetStapleInterface is not known to the MoverFactory. Was it registered via a MoverRegistrator in one of the init.cc files (devel/init.cc or protocols/init.cc)?

Best wishes,

Is the packer aware of non canonical amino acids?

Category: 
Design

I am having a problem when setting the packer to design residues that are non canonical in the pdb file I provide. I have an example for 2ovq where the short peptide called chain C has two phosphorylated residues (TPO at 380 and SEP at 384). When I make a resfile like this:

NATAA
start
384 C ALLAA

Loop Modeling

Hi,

I am using the 2016.28 build and have the some problems with "BridgeChainsMover" from Brian's recent method paper: DOI:10.1007/978-1-4939-3569-7_20

I get this error "ERROR: 'scorefxn' is not a valid option for BridgeChainsMover".  Here is the part of script that returns an error:

<BridgeChainsMover name="connect" chain1="1" chain2="2" motif="3LX-3LA-3LX" overlap="3" scorefxn="centroid_scorefunction" />

reporting IteratedConvergence status

Category: 
Scoring

Dear All,

I use IteratedConvergence in my Rosetta Script. Is there a convenient way to monitor the number of cycles that that passed before the convergence? Would it be possible to have this value for the individual models in the score file, together with total_score etc.?

This brings a more general question - how to monitor/debug Rosetta scripts, e.g. track energy values, behavior of filters etc.

Thank you for suggestions & best wishes,

Staszek

Error during scons building

Category: 
Compilation

I've been trying to build the latest weekly release (2016.20), and after starting scons using:

external/scons-local/scons.py -j3 mode=release bin 

from the source directory, everything will be fine for around 2h, but then I get this error:

/usr/bin/ld: cannot find -lz
collect2: error: ld returned 1 exit status
scons: *** [build/src/release/linux/3.2/64/x86/gcc/4.7/default/libObjexxFCL.so] Error 1
scons: building terminated because of errors.

short peptide fragment file generation

Category: 
Fragment Generation

Hi Rosetta users,

I was trying to generate fragment files for a short peptide (9-AA) for use in abinito FlexPepDock. I checked out the demo, but found it quite difficult to follow using make_fragments.pl. I learned from the forum that the perl script is a bit outdated and we should use either the Robetta server or the new fragment picker application.  However, Robetta doesn't seem to accept very short sequences. Could anyone advise me how to use the new fragment picker application to generate fragments for short peptides. Thanks in advance!

multiple symmetry definition files

Category: 
Symmetry

Hello,

Multiple input structures are provided as a list (in:file:l) or in a single silent file (in:file:silent).

Is there an easy way to provide also symmetry definition files for the individual structures? (symmetry:symmetry_definition)

Thanks you for suggestions!

Best wishes,

Staszek

PyRosetta memory footprint

Category: 
PyRosetta

Hi All,

I have a design protocol implemented in PyRosetta that has a very large memory footprint ~ 4Gb. I ran a python memory profiler on the design script and discovered that the sharp memory consumption increase occurs upon the initialization of PackRotamerMover (I presume this is where the rotamer library is instantiated). I have taken the following measures to reduce the memory consumption with no success:
