RSHtune

Installation

In order to be able to use this library, add the following to your .bashrc file:

export PYTHONPATH=$PYTHONPATH:<path/to/RSHtune>

The Makefile included with the package will both do this and source the modified .bashrc file for the current session when invoked using

make install

Basic Usage

The driver.py file provides a interface for the three most common taskt in tuning an RSH functional:

  • Run a single tuning calculation (neutral, anion, cation) at a given range separation parameter value, omega, and calculate the optimal tuning error.
  • Run a series of tuning calculations over a range of values for omega and tabulate the optimal tuning error for each.
  • Tabulate the optimal tuning error values based on prior calculations, already present in a given directory.

Command Line Arguments

Argument Required Function
--inputFile yes Input file for the neutral species. Note: respects --dir.
--dir no Directory in which to carry out tuning, store and locate files.
--dry no Tabulate preexisting tuning results only, no calculations.
--omega no Carry out a single tuning calculation at omega.
--omegaRange no Tune over a range of values for omega. Conflicts with --omega!
--numThreads no Number of threads to run QChem with. Default: 1
--multiplicities no Specify spin-multiplicities: neutral anion cation
