## Does Rosetta have homology modeling protocol?

Hi all,

Does Rosetta have a homology modeling protocol like SWISS-MODEL or MODELLER? I couldn't find it in source code.
I want to predict the structure of a sequence and then do a protein-protein docking, need I use MODELLER to create the structure from sequence and template pdb before repacking or loop modeling using Rosetta?

Thanks.

## Fundamental methods: pose.residue().total_atom(), pose.atom(#) ?

Are there any methods that can return the total number of atoms in the pose? I am trying to do a simple operation, like shift a peptide some distance along a certain vector, and find myself unable to loop over atoms in the simulation.

Is there a resource that lists all the methods accessible from the Rosetta python library?

How can I solve these problem? Could someone tell me! Thank you very much!

## Problem while unzipping the source code

I intend to install Rosetta version 3.1 for Windows. However problem started even at the time of unzipping the source rosetta3.1_source.tgz :-((

The warning message tells:
rosetta_source\ide\test\utility\pointer\ folder does not exist. Do you want to create it? on either yes or no it's terminating generating the following error message. The unzipping is incomplete and the Bin, Lib folders are empty

## Backrub patch

Hi,

When I add the rosetta3.1_backrub_patch35535 rosetta can't compile.
It complains about the new SidechainMover.cc:

## Running Backrub

Hi, I have a startup problem with the backrub application: The -ntrials option gives me an error: "ERROR: Unique best command line context option match not found for -ntrials" as if this option was given twice? I checked this so what am I doing wrong? Thanks!

## Introduction or tutorial about RosettaMatch

I am interested in protein design with RosettaMatch algorithm. But It is difficult for me to figure out how to use this algorithm in Rosetta 3.1. Is there any introduction or tutorial about how to use RosettaMatch? Any suggestion is welcome.

## error in installation

hi everyone

I am trying to install rosetta on ubuntu maverick (10.10) and having troubles with it .... I tried to install with a lower version of gcc-4.2 (as suggested in the installation guide) instead of the gcc-4.4 (default for maverick) but it is giving the same error at one file:

/src/core/scoring/sasa.cc: 618 internal compiler error: Segmentation fault

is there anyone facing the same problem or know anything about how I go about solving it .. please let me know

cheers

## Mac OSX installation

Hi everyone,

Here I'm sharing my frustration with using this module on Mac, with the hope of saving you some time, or finding a solution:

The library files (.so & dylib files) included in the package are ONLY compatible with the python 2.5 (and no other version) that is shipped with Mac OS.
This is a serious problem as many basic modules (e.g. numpy & scipy) are not compatible with this python and require standard version of python from python.org.
Here are some tricks that didn't work:
