# Dataset Card for SLAF Dataset |
|
|
|
|
|
## Dataset Description |
|
|
|
|
|
Single-cell data in SLAF (Sparse Lazy Array Format) format. Contains 317 files with total size 0.68 GB. |
|
|
|
|
|
## Usage |
|
|
|
|
|
This dataset is in [SLAF (Sparse Lazy Array Format)](https://slaf-project.github.io/slaf/) format, which uses the [Lance](https://lance.org/) table format for storage. |
|
|
You can use it with either the `slafdb` library (for SLAF format) or `pylance` library (for direct Lance access). |
|
|
|
|
|
### Using SLAF (Recommended) |
|
|
|
|
|
```bash |
|
|
pip install slafdb |
|
|
``` |
|
|
|
|
|
```python |
|
|
hf_path = 'hf://datasets/pavan-ramkumar/test_direct_upload.slaf' |
|
|
from slaf import SLAFArray |
|
|
slaf_array = SLAFArray(hf_path) |
|
|
slaf_array.query("SELECT * FROM cells LIMIT 5") |
|
|
``` |
|
|
|
|
|
### Using Lance Directly |
|
|
|
|
|
```bash |
|
|
pip install pylance |
|
|
``` |
|
|
|
|
|
```python |
|
|
import lance |
|
|
hf_path = 'hf://datasets/pavan-ramkumar/test_direct_upload.slaf' |
|
|
ds = lance.dataset(f"{hf_path}/cells.lance") |
|
|
ds.sample(10) |
|
|
``` |
