How to calculate dG?

Submitted by yperez on Mon, 2012-10-22 07:28

Hi all,
I have modeled some mutations with the Backrub application and would like to calculate dG of folding (to do somthing similar to ddG monomer application). Is there a way to do this? Thanks.

AtomTree::torsion_angle() can't find dof! in match and enzdes

Submitted by petrikigor on Fri, 2012-10-19 09:49

I am running matcher and enzdes using a complex ligand. I keep getting the following lines repeating throughout my output files in both matching and enzdes:
core.kinematics.AtomTree: AtomTree::torsion_angle() cant find dof! atomno= 6 rsd= 5 atomno= 9 rsd= 5 atomno= 10 rsd= 5 atomno= 11 rsd= 5 core.kinematics.AtomTree: AtomTree::torsion_angle() cant find dof! atomno= 6 rsd= 5 atomno= 9 rsd= 5 atomno= 14 rsd= 5 atomno= 15 rsd= 5

Unknow atom_name: LYS 1HZ in enzdes after match

Submitted by petrikigor on Fri, 2012-10-19 09:35

I am trying to run enzyme design on one of the models that I got from a matcher run, but it fails with the following:
protocols.toolbox.match_enzdes_util.EnzConstraintParameters: for block 1, 1 newly generated constraints were added protocols.toolbox.match_enzdes_util.EnzConstraintIO: checking cst data consistency for block 1... done protocols.toolbox.match_enzdes_util.EnzConstraintIO: Cst Block 1done... protocols.toolbox.match_enzdes_util.EnzConstraintParameters: for block 2, 1 newly generated constraints were added

Error when importing protocols.simple_filters

Submitted by xfliu on Tue, 2012-10-16 13:37

Hi,

I'm trying to access ddG filter in PyRosseta. But it seems that the simple_filters module is not implemented in current PyRosetta r51661, because the following errors occurred when I trying do so:

>>> from rosetta import *
>>> import rosetta.protocols.simple_filters

Traceback (most recent call last):
File "", line 1, in
import rosetta.protocols.simple_filters
File "D:\Program Files\PyRosetta\rosetta\protocols\simple_filters\__init__.py", line 1, in
from __simple_filters_all_at_once_ import *

Fixbb Multiple Resfiles

Submitted by protos_heis on Mon, 2012-10-15 10:34

I was wondering if it is possible to specify multiple resfiles in a single fixbb job submission. For instance, if I have 10 resfiles and 10 PDBs I would like to have 100 output files, 10 for each resfile. If not is there a simple way to modify the code to do this? I tried writing a wrapper program for the main function in fixbb.cc that cycles resfiles in and out of the flags file and calls the main function passing that in as argv, but the second call to the main function (second resfile) crashes with an error message saying:

Symmetric Processing for evaluating side-chain of chi angle

Submitted by qlj on Wed, 2012-10-10 04:08

I have some problems about evaluating side-chain of chi angle. I used executable file of "relax" to repack side-chain, then I want to evaluate the number of chi angles which are lower than 40 degrees comparing with native angle. I associate something, as follows:
1、amino acids ,like ASP , GLU, PHE, TYR, ARG, etc ,having symmetry, are evaluated with symmetrical processing, in order to avoid error calculation coursed by the numbers of the same atomic.

computer specifications

Submitted by rlwoltz on Tue, 2012-10-09 16:11

I am buying a computer specifically to run protein folding predictions and protein docking predictions. I am using a computer now that has 4GB of RAM and a 3.33 Ghz processor. However I seem to be running out of memory on some of the models, I can only run one or maybe two at a time, and the abinitio algorithm for a 80 aa protein takes 3 weeks for 10000n. Does anyone know what the recommended size and specs for a decent computer to do this work using Rosetta 3.4 would be?

Thanks
Ryan
