Residue Interaction Network-based ResidUe Selector (RINRUS) is a QM-cluster model building tool. Starting from a raw PDB file, after running a series of preparation tasks, the tool will
- select important residues for chemical reactions, and
- generate trimmed PDB files with the corresponding quantum chemical inputs.
Clone this repository, then add the library code under lib3
to your PYTHONPATH
. For example, in ~/git
:
cd ~/git
git clone git@github.com:natedey/RINRUS.git
export PYTHONPATH="~/git/RINRUS/lib3:$PYTHONPATH"
- Python >= 3.x
- NumPy
- pymol
- If installing via conda, it's under
-c conda-forge pymol-open-source
.
- If installing via conda, it's under
- openbabel (required for Arpeggio)
For certain scripts (optional),
- matplotlib
- BioPython
- probe - version 2.16.130520 is packaged with RINRUS
- reduce - version 3.23 is packaged with RINRUS
- arpeggio
Currently, a precompiled copy of each is present in bin/
.
which require
- CMake >= 3.10
- Any C/C++ compiler suite with C++11 support
Currently, RINRUS can generate appropriate QM-cluster model input files for
-Gaussian09/Gaussian16
-the Gaussian-xTB wrapper developed by the Asparu-Guzik group (https://github.com/aspuru-guzik-group/xtb-gaussian)
-Q-Chem 5.x/6.x
TODO:
-write QM/MM input files with RINRUS-designed QM regions
-write I/FSAPT input files in PSI4 (scripts to process PSI4 FSAPT calculations and build QM-cluster models of enzymes with non-covalently bonded substrates are available)
-write ORCA and TURBOMOLE QM-cluster model input files
-automated network graph visualization of RINRUS models
Current production-level use cases are described in bin/
with tutorials in bin/README.md
The first public release (version 0.2) includes examples 1 and 2 only! Examples 3 - 5 will be available soon.
Usage example 4 - generating a single or a few input files with manual ranking (from SAPT, ML, or from some scheme that doesn't yet interface with RINRUS automatically)
This code has been developed by the DeYonker group at the University of Memphis Department of Chemistry.
