Installing the development version

To use the most recent IgDiscover version from Git, first follow the regular installation instructions. Then do the following:

  1. Uninstall the igdiscover package with:

    conda uninstall igdiscover

    This removes igdiscover itself, but the dependencies remain (IgBLAST etc.), which is what we need.

  2. Clone the repository:

    git clone

    (Use the git@ URL instead if you are a developer.)

  3. Install IgDiscover:

    cd IgDiscover
    python3 -m pip install -e .

If you are a developer, you may also want to look into Conda environments and use those.

Whenever you want to update the software:

cd IgDiscover
git pull

It may also be necessary to repeat the python3 -m pip install -e . step.

Building the documentation

Go to the doc/ directory in the repository, then run:


to build the documentation locally. Open _build/html/index.html in a browser. The layout is different from the version shown on Read the Docs, but allows you to preview any changes you may have made.

Making a release

We use versioneer to manage version numbers. It extracts the version number from the most recent tag in Git. Thus, to increment the version number, create a Git tag:

git tag v0.5

The v prefix is mandatory.

Removing IgDiscover from a Linux system

If you have been playing around with different installation methods (pip, conda, git, python3 install etc.) you may have multiple copies of IgDiscover on your system and you will likely run into problems on updates. Here is a list you can follow in order to get rid of the installations as preparation for a clean re-install. Do not add sudo to the commands below if you get permission problems, unless explicitly told to do so! If one of the steps does not work, that is fine, just continue.

  1. Delete miniconda: Run the command which conda. The output will be something like /home/myusername/miniconda3/bin/conda. The part before bin/conda is the miniconda installation directory. Delete that folder. In this case, you would need to delete miniconda3 in /home/myusername.
  2. Run pip3 uninstall igdiscover. If this runs successfully and prints some messages about removing files, then repeat the same command! Do this until you get a message telling you that the package cannot be uninstalled because it is not installed.
  3. Repeat the previous step, but with pip3 uninstall sqt.
  4. If you have a directory named .local within your home directory, you may want to rename it: mv .local dot-local-backup You can also delete it, but there is a small risk that other software (not IgDiscover) uses that directory. The directory is hidden, so a normal ls will not show it. Use ls -la while in your home directory to see it.
  5. If you have ever used sudo to install IgDiscover, you may have an installation in /usr/local/. You can try to remove it with sudo pip3 uninstall igdiscover.
  6. Delete the cloned Git repository if you have one. This is the directory in which you run git pull.

Finally, you can follow the normal installation instructions and then the developer installation instructions.
