Hi Knut,
The Meiler lab uses a cleaning script that was created by:
1. Phil Bradley
2. Rhiju Das
3. Michael Tyka
4. TJ Brunette
5. James Thompson
The script was modified to work with the Meiler lab configuration. James Thompson has included the cleaning script in the Rosetta 3.2 release. You can find the script in your rosetta_source directory: rosetta-3.2/rosetta_source/src/python/apps/public/get_pdb.py
In general, you run it by: python get_pdb.py
