brainglobe-workflows is a package that provides users with a number of out-of-the-box data analysis workflows employed in neuroscience, implemented using BrainGlobe tools.

These workflows represent the most common use-cases and are meant to be easy to reuse. They also serve as an example of how to combine several BrainGlobe tools (possibly together with other tools) to achieve a goal, such as whole brain cell detection and atlas registration.

You can view the full documentation for each workflow online. You can also find the documentation for the backend BrainGlobe tools these workflows use on our website.

At present, the package offers the following workflows to users:

• brainmapper: A command-line tool for whole-brain detection, registration, and analysis.

Additionally, this repository provides functionalities to support code developers. See the developer documentation for further details.

At the moment, users can install all available workflows by running pip install in your desired environment:

pip install brainglobe-workflows

brainglobe-workflows is built using BrainGlobe tools, and it will automatically fetch the tools that it needs and install them into your environment. Once BrainGlobe version 1 is available, this package will fetch all BrainGlobe tools and handle their install into your environment, to prevent potential conflicts from partial installs.

See the sections below for more information about the workflows and command-line tools provided.

Whole-brain cell detection, registration and analysis.

If you want to just use the cell detection part of brainmapper, please see the standalone cellfinder package and its napari plugin.

brainmapper is a workflow designed for the analysis of whole-brain imaging data such as serial-section imaging and lightsheet imaging in cleared tissue. The aim is to provide a single solution for:

• Cell detection (initial cell candidate detection and refinement using deep learning) (using the cellfinder backend package),
• Atlas registration (using brainreg),
• Analysis of cell positions in a common space.

Basic usage:

brainmapper -s signal_images -b background_images -o output_dir --metadata metadata

Full documentation can be found here.

NOTE: The brainmapper workflow previously used the name "cellfinder", but this has been discontinued following the release of the unified cellfinder backend package to avoid conflation of terms. See our blog post from the release for more information.

This repository also includes code to benchmark typical workflows. These benchmarks are meant to be run regularly, to ensure performance is stable as the tools are developed and extended.

There are three main ways in which these benchmarks can be useful to developers:

1. Developers can run the available benchmarks locally on a small test dataset.
2. Developers can also run these benchmarks on data they have stored locally.
3. We also plan to run the benchmarks on an internal runner using a larger dataset, of the scale we expect users to be handling. The result of these benchmarks will be made publicly available.

For further details on how to run the benchmarks, see the benchmarks README.

We are always happy to help users of our tools, and welcome any contributions. If you would like to get in contact with us for any reason, please see the contact page of our website.

If you use any tools in the brainglobe suite, please let us know, and we'd be happy to promote your paper/talk etc.
