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:

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-.

Note

These instructions are for newinstall.sh- 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 `https://eups.lsst.codes/stack/src/tags/`_.
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.

To see what packages (and their versions) are currently set up:

eups list -s

To see all packages that are installed, even if not currently set up, run:

eups list
