brainglobe-atlasapi works with Python >3.6, and can be installed from PyPI with:
pip install brainglobe-atlasapiFull information can be found in the documentation

# ╰──────────────────────────────────┴────────────┴───────────────┴──────────────╯All the features of each atlas can be accessed via the BrainGlobeAtlas class.
e.g. for the 25um Allen Mouse Brain Atlas:
from brainglobe_atlasapi.bg_atlas import BrainGlobeAtlas
atlas = BrainGlobeAtlas("allen_mouse_25um")The various files associated with the atlas can then be accessed as attributes of the class:
# reference image
reference_image = atlas.reference
print(reference_image.shape)
# (528, 320, 456)
# annotation image
annotation_image = atlas.annotation
print(annotation_image.shape)
# (528, 320, 456)
# a hemispheres image (value 1 in left hemisphere, 2 in right) can be generated
hemispheres_image = atlas.hemispheres
print(hemispheres_image.shape)
# (528, 320, 456)There are multiple ways to work with individual brain regions. To see a dataframe of each brain region, with it's unique ID, acronym and full name, use atlas.lookup_df:
atlas.lookup_df.head(8)
# acronym id name
# 0 root 997 root
# 1 grey 8 Basic cell groups and regions
# 2 CH 567 Cerebrum
# 3 CTX 688 Cerebral cortex
# 4 CTXpl 695 Cortical plate
# 5 Isocortex 315 Isocortex
# 6 FRP 184 Frontal pole, cerebral cortex
# 7 FRP1 68 Frontal pole, layer 1Each brain region can also be access by the acronym, e.g. for primary visual cortex (VISp):
from pprint import pprint
VISp = atlas.structures["VISp"]
pprint(VISp)
# {'acronym': 'VISp',
# 'id': 385,
# 'mesh': None,
# 'mesh_filename': PosixPath('/home/user/.brainglobe/allen_mouse_25um_v0.3/meshes/385.obj'),
# 'name': 'Primary visual area',
# 'rgb_triplet': [8, 133, 140],
# 'structure_id_path': [997, 8, 567, 688, 695, 315, 669, 385]}Working with both image coordinates and cartesian coordinates in the same space can be confusing!
In brainglobe-atlasapi, the origin is always assumed to be in the upper left corner of the image (sectioning along the first dimension), the "ij" convention.
This means that when plotting meshes and points using cartesian systems, you might encounter confusing behaviors coming from the fact that in cartesian plots one axis is inverted with respect to ij coordinates (vertical axis increases going up, image row indexes increase going down).
To make things as consistent as possible, in brainglobe-atlasapi the 0 of the meshes coordinates is assumed to coincide with the 0 index of the images stack, and meshes coordinates increase following the direction stack indexes increase.
To deal with transformations between your data space and brainglobe-atlasapi, you might find the brainglobe-space package helpful.

For full instructions to add a new BrainGlobe atlas, please see here.
The brainglobe_atlasapi.atlas_generation submodule contains code for the generation of cleaned-up data, for the main brainglobe_atlasapi module.
This code was previously the bg-atlasgen module.
- Fork this repo
- Clone your repo
- Run
git clone https://github.com/brainglobe/brainglobe-atlasapi - Install an editable version of the package; by running
pip install -e .within the cloned directory - Create a script to package your atlas, and place into
brainglobe_atlasapi/atlas_generation/atlas_scripts. Please see other scripts for examples.
Your script should contain everything required to run. The raw data should be hosted on a publicly accessible repository so that anyone can run the script to recreate the atlas.
If you need to add any dependencies, please add them as an extra in the pyproject.toml file, e.g.:
[project.optional-dependencies]
allenmouse = ["allensdk"]
newatlas = ["dependency_1", "dependency_2"]
