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) format, which uses the Lance 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)

pip install slafdb

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

pip install pylance

import lance
hf_path = 'hf://datasets/pavan-ramkumar/test_direct_upload.slaf'
ds = lance.dataset(f"{hf_path}/cells.lance")
ds.sample(10)
