## brainglobe-template-builder

An example nifti file, courtesy of [Sirmpilatze et al.,2021](https://doi.org/10.5281/zenodo.6510880) and its N4-brightness corrected outputs, for regression testing against ground truth.
The N4 bias field correction was performed by running the `n4_script.py` from 
within the `brainglobe-template-builder` directory. The required `antspyx`
version is specified within the script as per [PEP 723](https://peps.python.org/pep-0723/).

```python
cd brainglobe-template-builder
uv run n4_script.py
```
