Homology modeling
#1

Hello,

Is there good documentation or a tutorial on how to use Rosetta 3.0 to construct a homology model based on a user-input template?

Documentation is not clear (or is absent).

Any help is most welcomed. I am able to generate a backbone model, but unable to generate a fullatom model.

thanks, Mike

The error I am getting when running the following:

/usr/local/rosetta3.0/bin/loopmodel.gcc.i686
-database /usr/local/rosetta3.0/rosetta3_database
-nstruct 2
-in:file:fullatom

-out:file:fullatom

is:

"ERROR: Could not find disulfide partner for residue"

Do you have disulfides in your protein?

As of 3.0, the "detect_disulfides" flag defaults to true, you can try turning this to false, especially if you do not have disulfides.

There is a flag "fix_disulf" which lets you specify where you know the disulfides are - I've never used it and have no idea if it's compatible with loop modeling.
