Setting up installed LSST Science Pipelines

Whenever you start a new command-line shell, you need to set up the LSST Science Pipelines software before you can use it.

Setting up

Setting the LSST Science Pipelines in a shell is a two-step process:

  1. Load the LSST environment by sourcing the loadLSST script in your installation directory:

    source loadLSST.bash # for bash
    source loadLSST.csh  # for csh
    source loadLSST.ksh  # for ksh
    source loadLSST.zsh  # for zsh

    To customize the conda environment used, set the LSST_CONDA_ENV_NAME environment variable to a conda enviroment name when sourcing the file. For other conda environments installed by LSST tools, this name will be the rubin-env metapackage version prefixed with lsst-scipipe-.


    These installation are for and Install with lsstinstall and eups distrib-based installations. For lsstsw, follow these instructions instead.

    To find the rubin-env conda metapackage version appropriate for a particular science pipelines release, see Release History or the release tag files at ``_.

  2. Set up a top-level package:

    setup <package>

    For example, setup lsst_apps or setup lsst_distrib. See Top-level packages to install for more about LSST’s top-level packages.
