Python scripts to use Allen Brain Map data for analysis and rendering
Project description
BrainRender
brainrender
is a python package for the visualization of three dimensional neuroanatomical data.
It can be used to render data from publicly available dataset (e.g. Allen Brain atlas) as well as user generated experimental data.
The goal of brainrender is to faciliate the exploration and dissemination of neuroanatomical data by providing a user-friendly platform to create high-quality 3D renderings.
For more information about brainrender
and how to use it, please check the brainrender docs.
You can also have a look at the brainrender preprint and the examples and tutorials.
You can find interactive examples of data visualisations generated with brainrender here and a gallery of images created with brainrender here.
Installation
To install brainrender
, you use an existing python environment or create a new one [with python < 3.8
]. Then simply install with:
pip install brainrender - U
If you want the most recent version of brainrender
's code, you can get it directly from github with:
pip install -U git+https://github.com/BrancoLab/BrainRender.git
To quickly check that everything worked for your installation, try creating a brainrender scene directly from the terminal.
brainrender TH STR -c
Usage
brainrender
relies on brainglobe's brainatlas-api to fetch structural and morphological data for various brain atlases, including two mice atlases, one zebrafish atlas and one atlas of the human brain. Much of what brainrender can do works across all of these atlases. Basic functionality supported by brainrender
inclused the display of anatomical brain region, the position of labelled cells from tracking experiments (e.g. as obtained with tools like cellfinder) and whole-cell neuronal morphological reconstructions. Click on the images below to see aexamples of how to use brainrender:

Mouse brain-specific
Some of brainrenders functionality is specific to the atlases based on the Allen mouse brain atlas. This includes functionality to render publicly available as well as user-generated data.
Publicly available datasets
Brainrender can be used to download a visualize a neuroanatomical data from several publicly available datasets based on the Allen Atlas of the mouse brain. Anatomical and projection data is downloaded from the Allen Brain Atlas reference atlas and connectivity atlas using the Allen API (© 2015 Allen Institute for Brain Science. Allen Brain Atlas API. Available from: https://brain-map.org/api/index.html) ([1], [2]). Brainrender can also be used to download and visualise gene expression data from the Allen database and neurons morphological data from Janelia's mouse light project (see the neurons browser). [3]

User generated
brainrender
can be used to visualise the location of implanted neuropixel probes with data from SHARP TRACK.

Exporting
To facilitate the creation of scientific illustrations, brainrender let's you take screenshots of your scenes, create animated videos and embed interactive visualisations scenes in your website.
To learn how to do it, check these examples:
Other
brainrender
relies on the powerful vedo
(https://vedo.embl.es) (github) rendering engine, thus providing you with the flexibility to render just about anything you might need for your visualisation. As an example, here you can see how to visualise the location of an implanted optic fiber or any other 3d object from an .stl
or .obj
file.
Optic fibre | .stl file visualisation | .obj file visualisation |
---|---|---|
add_optic_cannula.py |
add_object_to_scene.py |
add_object_to_scene.py |
A few more things you can do to improve your visualizations:
- reveal what's inside a 3d object by cutting it in half.
- add a title or 3d text to your scene
- label elements in your scene, so that you always know what you're looking at.
- create multiscenes to look at several pieces of data at once.
- change the overall look of your scenes
- and more...
Other atlases
In addition to the atlases supported by brainatlas-api
, you can easily create new Atlas
classes to support the visualisation of your own datasets in brainrender
(see here for more details). As a way of example we provide two such classes. One to visualise insect brains from insectbraindb.org and one for C. Elegans connectome data from Daniel Witvliet's recent preprint.

Getting in touch
If you're unsure how to use brainrender
, please start by having a look at the user guide and the examples notebooks. If you still have unanswered questions, please do not hesitate to get in touch (the easiest way is to open an issue on github).
For any bug report or feature request, please open an issue with a brief description of the matter. Although brainrender can already to much, we are always happy to add more functionality that could be useful for users. If you spot some feature that is missing, we'd love to hear about is so please get in touch!

Behind the scenes
Brainrender was deisgned to be a powerful and flexible software for downloading and rendering neuroanatomical data while still being relatively easy to use (using brainrender requires minimal coding experience). This was achieved by:
- handling the interaction with the API, SDK and databases services used to find and download the data behind the scenes, requiring minimal user input.
- Using vedo to handle the rendering. vedo (github repo) is a powerful rendering engine that produces high quality three dimensional rendering. vedo is also flexible, meaning that it can handle data provided in various file formats, allowing
brainrender
to render data from various sources.
