ham2spec 0.4.0

A Python extension for computing spectra from Hamiltonians

ham2spec

This is a Python extension written in Rust using PyO3 and maturin.

This module computes absorption and circular dichroism (CD) spectra from a Hamiltonian and a set of pigment positions and transition dipole moments. It's primarily used by the fmo_analysis tool.

Installation

Right now this only works on macOS because I only have a macOS system to test on. The primary hurdle to building on other systems is the dependency on LAPACK. Your system will need to have a LAPACK implementation installed, and you'll need to set the correct lapack_src feature.

Development

The Python extension module requires a crate-type of "cdylib", but running examples and requires a crate-type of "rlib". In order to accommodate both you'll need to run tests via

$ cargo test --lib

and examples via

$ cargo run --no-default-features --example example_name
