Or, if preferred, installed into its own environment via:
conda create -n thor_py38 -c moeyensj thor python=3.8


A Docker container with the latest version of the code can be pulled using:

docker pull moeyensj/thor:latest

To run the container:

docker run -it moeyensj/thor:latest

The THOR code is installed the /projects directory, and is by default also installed in the container's Python installation. To access the code in Python:

To install THOR in its own conda enviroment please do the following:

conda create -n thor_py38 -c defaults -c conda-forge -c astropy -c moeyensj --file requirements.txt python=3.8

Or, to install THOR in a pre-existing conda environment called env:

conda activate env
conda install -c defaults -c conda-forge -c astropy -c moeyensj --file requirements.txt

Once pre-requisites have been installed using either one of the options above, then:

python install

Or, if you are actively planning to develop or contribute to THOR, then:

python develop --no-deps

You should now be able to start Python and import THOR.
