This directory contains a small set of randomly selected sample files from the large-scale [CORAL](https://huggingface.co/datasets/yangzekang2000/CORAL) dataset, a whole-brain neuron tracing benchmark. These samples are provided as lightweight examples for quick inspection, visualization, and testing of different CORAL data types without downloading the full dataset.
## Directory Structure
```text
CORAL-samples/
├── cubes-5/ # 5 block-level task samples with 3D cubes, SWC annotations, and mask labels
├── slices-5/ # 5 whole-brain 2D slice image samples
└── neuron-swcs-3/ # 3 complete single-neuron SWC annotations
```
## Data Description
- `cubes-5/`
- Contains 5 examples for CORAL block-level tasks.
- Each example includes a 3D cube image block in `.tif` format.
- Files with the same basename and the `.swc` extension are the corresponding neuron structure annotations.
- Files with the same basename and the `_mask.tif` suffix are the corresponding mask annotations.
- `slices-5/`
- Contains 5 randomly selected 2D slices from whole-brain image data in `.tif` format.
- `neuron-swcs-3/`
- Contains 3 complete neuron annotations in `.swc` format.
- These files provide examples of full-neuron morphology labels from CORAL.
