This project contains tools to split brain atlas regions and refine annotations accordingly.

After installation, you can display the available command lines with the following bash command:

atlas-splitter --help

pip install atlas-splitter

To split the layer 2/3 of the AIBS mouse isocortex and save modified hierarchy and annotation files, one performs the following:

Note that the required datasets under data/* can be generated by following the example in atlas-direction-vectors.

atlas-splitter split-isocortex-layer-23                         \
  --hierarchy-path data/1.json                                  \
  --annotation-path data/ccfv3/annotation_25.nrrd               \
  --direction-vectors-path data/ccfv3/direction_vectors.nrrd    \
  --output-hierarchy-path data/ccfv3/split_hierarchy.json        \
  --output-annotation-path data/ccfv3/split_annotations.nrrd

To add barrel annotations to the Barrel Cortex and save modified hierarchy and annotation files, one performs the following:

atlas-splitter split-barrel-columns                        \
  --hierarchy-path data/1.json                                  \
  --annotation-path data/ccfv3/annotation_25.nrrd               \
  --barrels-path data/barrel_positions.feather                   \
  --output-hierarchy-path data/ccfv3/split_hierarchy.json        \
  --output-annotation-path data/ccfv3/split_annotations.nrrd

Run the following commands before submitting your code for review:

cd atlas-splitter
isort -l 100 --profile black atlas_splitter tests setup.py
black -l 100 atlas_splitter tests setup.py

These formatting operations will help you pass the linting check testenv:lint defined in tox.ini.
