If you find the tools helpful, you can cite the repo using the DOI above :-)

A library and a program to run various Python functions related to work with PDB files of RNA structures.

The software is used by me in my servers NPDock (RNA/DNA-protein docking method, http://genesilico.pl/NPDock/) and SimRNAweb (RNA 3D structure prediction method, http://iimcb.genesilico.pl/SimRNAweb/) and mqapRNA (RNA 3D quality control, http://iimcb.genesilico.pl/mqapRNA/, in progress)

What is fun here?

you see input & output -- this is what you want to get?
it's tested via Travis! -- it (should) always works as you just want!
you lack a converter you would like to have one? Just Do It Yourself - compose your converter/parser from LEGO brick-like functions, see for example --rosetta2generic)

.. or you might want to use the lib in the program.

RNA Puzzle Submission

Prepare your structures in the folder and run to get them RNApuzzle ready (_rpr):

$ for i in `ls *.pdb`; do rna-pdb-tools.py --get_rnapuzzle_ready $i > ${i/.pdb/_rpr.pdb}; done

.. merge them as one file in the order as you like (or use *):

$ rna-pdb-merge-into-one.py 02_19pz_v1_SimRNA3.22_thrs6.60A_clust02-000001_AA_out_rpr.pdb 09_19pz_v2_SimRNA3.22_thrs6.60A_clust03-000001_AA_out_rpr.pdb d311d821-a075-4df0-bd7d-1dcf7669dad9_ALL_thrs6.20A_clust01-000001_AA_out_rpr.pdb d311d821-a075-4df0-bd7d-1dcf7669dad9_ALL_thrs6.20A_clust03-000001_AA_out_rpr.pdb 05_19pz_v1_SimRNA4.xx_thrs6.60A_clust02-000001_AA_out_rpr.pdb  > rp19_bujnicki.pdb

and verify your file with the template provided by the organizers:

$ diffpdb --method diff Reference_19.pdb rp19_bujnicki.pdb
#<empty = no difference but xyz columns, OK!>

diffpdb is a part of the rna-pdb-tools package.

Tricks

$ for i in *; do echo $i; rna-pdb-tools.py --delete A:48-52 $i > noloop/${i/.pdb/_noloop.pdb}; done
10_rp17c.out.14.pdb
10_rp17c.out.14_out.pdb
[..]

$ for i in `ls *.pdb`; do rna-pdb-tools.py --c $i > ${i/.pdb/_clx.pdb}; done

$ for i in `ls *.pdb`; do rna-pdb-tools.py --get_rnapuzzle_ready $i > ${i/.pdb/_rpr.pdb}; done

.. keep original structures in original and use rpr:

➜  bujnicki_server_ss for i in `ls original/*.pdb`; do rna-pdb-tools.py --get_rnapuzzle_ready $i > ${i/.pdb/_rpr.pdb}; done
➜  bujnicki_server_ss ls

Install

Install requirements and do these three steps:

add the path to the package to your PYTHONPATH (in ~/.bashrc), e.g. PYTHONPATH=$PYTHONPATH:/home/magnus/src/rna-pdb-tools/
add the path to the bin folder of the package to your PATH (in ~/.bashrc), e.g. PATH=$PATH:/home/magnus/src/rna-pdb-tools/bin/

and run the install script:

 ➜  rna-pdb-tools git:(master) ✗ ./install_links_bin.sh
 Installed in ./bin
 rmsd_calc_to_target.py

should be OK now :-)

Requirement

Some functions e.g. .get_rnapuzzle_ready() needs Biopython, rmsd calculations need numpy, .is_mol2() needs OpenBabel. Basically you should be asked to install anything extra only if you need a given function.

Used libraries

This packages uses other pieces of software, it would be impossible without them to develop rna-pdb-tools, thanks!

biopython (https://github.com/biopython/biopython)
rmsd (https://github.com/charnley/rmsd)
