install rosetta problems

I am trying install rosetta on the fedora system,with gcc 4.1.2 and scons 2.0.1. But I encountered a problem while I install with the command:scons bin mode=release.
there are two warnings that always repeat again and again, I do not know how to solve this problem.
scons: warning: The build_dir keyword has been deprecated; use the variant_dir keyword instead.
File "/xtal_programs/rosetta3.2.1/rosetta_source/SConscript", line 40, in

scons: warning: No hashlib or MD5 module available, CacheDir() not supported

Pyrosetta 2.0 - Dunbrak library binary not loading - strange repacking score


I am getting large energy increases when repacking a protein using v2.0 of PyRosetta.ScientificLinux64bit (I'm running RHEL5.5_64, Python 2.66)

abinitio - is there a way to limit number of CPU cores the program uses?

So the lab I'm working in has access to a 16 core server but we were told to use no more than 8 cores for any one application. So I was wondering if there is a way to limit the number of cores that abinitio uses while it runs its folding simulations? I looked through the help but didn't see anything that looked like it was what I'm looking for. Thanks for the help.

Pyrosetta energy function

I am considering various conformations of a given protein and I should compare their corresponding energy values. I have used Pyrosetta to compute the energies using the "scorefxn = create_score_function('standard')" command. I was under the impression that the PDB structure of a protein should have the minimum energy.

'DockingProtocol' object has no attribute 'setup_foldtree'

Hi around, sorry for disturbing with my problem that I haven't found posted or solved and if it has been solved I didn't find it. I recently downloaded PyRosetta and would like to use it for docking. The easiest, I thought, is to take an example script that comes with PyRosetta -, taking the test_dock.pdb that also comes with PyRsoetta and run it to get an idea about computational time. But it doesn't work by writing:
========= in ()
15 print "setting up docking fold tree"

Problem readin .ccp4 map file

Hi all,
I have bin trying to run the electron_density/molecular_replacement demo at step 4 and I get the following error. There is nothing wrong with the ccp4 map file (opens fine in other programs)but it appears to be looking for a MRC format map. How do I get the program to accept the ccp4 map?

core.scoring.electron_density.ElectronDensity: Loading Density Map
core.scoring.electron_density.ElectronDensity: [ ERROR ] Error opening MRC map MR.1_2mFo-DFc.ccp4. Not loading map.
