where is pdb2vall.py

[Anonymous]

Where can I find pdb2vall.py script to add extra pdb structures to the fragment libraries? I’ve searched through Rosetta3.4 bundle, Rosetta3.3_fragments and PyRosetta but couldn’t find it.

I can see it at ./rosetta_tools/fragment_tools/pdb2vall/pdb2vall.py. I’ve attached it.

In the README file from the pdb2vall folder:

3. Edit pdb2vall.cfg:

you need to modify the configuration file to give correct paths for scripts/databases.

In addition to reading the README and following the installation directions which includes editing the config file:

it looks like the script that installs/updates the PDB data (which is missing and causing the error) will only install/update Tues-Thursday to save bandwidth.

As a quick fix:

edit database/rcsb_data/update_rcsb_data.pl

by commenting out the line:

exit(0) if ($wday < 2 || $wday > 4);

line 10.

and then rerun the main pdb2vall script.
If that gives the same error, run ./database/rcsb_data/update_rcsb_data.pl and then rerun the main script.

Thanks.

I get an error I encountered with other python scripts from the Rosetta 3.4 bundle as well. I am using CentOS 6.3 64-bit, do you have any idea what package is needed?

$ python /home/thomas/Programs/Rosetta3.4/rosetta_tools/fragment_tools/pdb2vall/pdb2vall.py –help
Traceback (most recent call last):

I don’t have a copy of 3.4 tools handy. Using the developer-trunk version, it appears to be looking for “amino_acids.py” in the same directory. Is that not there for you? I can make you a copy of the whole directory.

EDIT: I looked into the 3.4 release…none of this stuff is there! I guess it’s newer than 3.4. I have made a copy of this whole directory off developer trunk for you and temporarily stashed it at http://rosettadesign.med.unc.edu/collaborators/RosettaTutorial/pdb2vall.tar.gz since it’s too large to attach. I’ll delete it after you signal that you downloaded it.

Thanks for the archive. I tried to run pdb2vall.py but got the following error:

$ python /home/thomas/Programs/Rosetta3.4/rosetta_tools/fragment_tools/pdb2vall/pdb2vall.py –no_structure_profile -d -p 4h99M

Is the directory you sent me complete?

[Anonymous]

The file “rosetta_tools/fragment_tools/pdb2vall/database/rcsb_data/derived_data/pdb_seqres.txt” does not exist in developer’s trunk. (The whole subdirectory derived_data does not exist). The README implies:

“
Databases which may need to be updated in the future:
…
database/rcsb_data:
derived_data ss_dis.txt
“

So apparently that file was either left out as incomplete, or you should supply an updated version somehow? I’ve contacted the code’s authors for comment.
