| # CORAL Samples |
|
|
| 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. |

|
| ## 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. |
