PyRad

This script package was developed for the creation and analysis of the radiolysis systems.

The main software to perform all TDDFT calculations: qb@ll (https://github.com/LLNL/qball) You will also need the packmol software to create systems (http://m3g.iqm.unicamp.br/packmol/home.shtml)

This repo includes:

1. PyRadCreator - creates an enviroment for radyolysis calculation in qb@ll software.

    Usage: PyRadCreator.py input1.ini input2.ini
    .ini files, and the host .xyz files should be placed in the same directory as this script.
    all pseudopotentials should be placed in pseudos directory
    WARNING! qb@ll doesn't respond to windows EOL symbol on unix-based systems!
   

2. PyRadTester - H2O radicals searcher with simple gui. Auto output of econst .csv file.

    Usage: PyRadTester.py qball_out.o
    For additional info about econst parameter see the url: 
    https://github.com/LLNL/qball/wiki/Tutorial-TDDFT#finding-the-optimal-time-step
   

3. PyRadEDensity - analyses the electron density .cube file and findes all anomalies in it.

    Usage: PyRadTester.py cube_file.o
   
    on GUI: symbols - atoms
            colored dots - electron density maxima
            sample size and threshold - sliders for maxima searcher
            correlation - slider to filter out electron density maxima that appear near atoms
   

4. Utils/PyRadDatAvrg.py is an additional utility for averaging several simulations.

    Usage: PyRadDatAvrg.py 1.sys 2.sys
    .sys-files can be generated by PyRadTester.
   

5. Utils/PyRadDatDraw.py is an utility to draw .sys file. It can be generated with PyRadTester

    Usage: PyRadDatDraw.py 1.sys
