A Python API for downloading and processing neuroanatomical atlas data from multiple sources.
BrainGlobe Atlas API (brainglobe-atlasapi) is a Python library that provides a common interface to download, access, and process neuroanatomical atlas data from multiple public sources. It solves the problem of fragmented and inconsistent atlas data formats by offering a unified API for researchers working with brain atlases across different species and imaging techniques.
Neuroscientists, bioinformaticians, and researchers who need programmatic access to standardized brain atlas data for analysis, visualization, or integration into computational pipelines.
Developers choose BrainGlobe Atlas API because it consolidates access to dozens of atlases through a single, well-documented Python interface, eliminating the need to write custom parsers for each data source and ensuring consistency in coordinate handling and data structures.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Provides a single BrainGlobeAtlas class to interact with over 20 atlases from sources like Allen, Max Planck, and Kim Lab, eliminating the need to learn separate APIs for each dataset.
Offers easy access to brain region IDs, acronyms, names, and 3D meshes through attributes like atlas.lookup_df and atlas.structures, as shown in the usage examples for region lookup.
Includes tools and guidelines in the atlas_generation submodule for contributing new atlases, with script examples and dependency management, fostering ecosystem growth.
Addresses common neuroimaging pain points by documenting image (ij) vs. cartesian coordinates and integrating with brainglobe-space for transformations, though external package use is required.
Requires downloading atlas data from public repositories at runtime, which can be slow, fail due to network issues, and ties availability to external server uptime.
Confined to Python environments, excluding researchers who use R, MATLAB, or other languages, and may complicate integration with non-Python tools or pipelines.
Adding a new atlas involves creating a script, managing optional dependencies in pyproject.toml, and hosting raw data publicly, which can be a barrier for casual contributors.
High-resolution atlases (e.g., 1-micron zebrafish) result in large file sizes; loading entire datasets into memory may cause issues, though the README doesn't address optimization strategies.
