Pyadjoint is an open-source Python package for calculating time-dependent misfit with a variety of misfit functions. It was designed to generate adjoint sources for full waveform inversion and adjoint tomography.
Although it can be used standalone, we recommend using Pyadjoint within the larger misfit quantification package Pyatoa.
Pyadjoint is hosted on GitHub as part of the adjTomo organization.
Have a look at the Pyadjoint usage page to get started, and browse available adjoint sources using the navigation bar.
We recommend Pyadjoint be installed inside a Conda environment.
git clone https://github.com/adjtomo/pyadjoint.git cd pyadjoint conda env create -n pyadjoint conda activate pyadjoint conda install obspy pip install -e .
Tests ensure Pyadjoint runs as expected after changes are made to the source code. You can run tests with Pytest.
cd pyadjoint/tests pytest
