pwfn 0.1.1
pwfn
pwfn is a tiny library for parsing AIMPAC
format .wfn files from quantum
chemistry programs and Molden2Aim
into a Python data structure. This can be used to do ML on electronic
wavefunctions.
This library does not do anything besides parsing! It is basically a single
page pyparsing grammar. You'll need
to do your own data processing from its outputs.
Usage
pwfn consists of a single string parser pwfn.loads(s),
import pwfn
with open("benzene.wfn", "r") as f:
wavefunction = pwfn.loads(f.read())
This returns a Wavefunction container with the extracted data in its
attributes. All quantities are in Hartree units (unchanged from the .wfn
format).
Installation
pwfn is available from pip,
pip install pwfn
It depends on the excellent
pyparsing library as well as
numpy.
Notes
If you want a similarly minimalist library to parse formatted checkpoint
files, consider my other library fchic.
If you are looking for a full feature solution for wavefunction data analysis,
consider using the excellent Multiwfn program
or orbkit.
