Usage
from huggingface_hub import hf_hub_download
import pandas as pd
# Download the expression data (Parquet - faster)
local_path = hf_hub_download(
repo_id="jruffle/tracerx_expression_data",
filename="tracerx_vst_counts.parquet",
repo_type="dataset"
)
# Load the data
expression_df = pd.read_parquet(local_path)
Data Format
- Index: Gene symbols (gene_id)
- Columns: Sample IDs
- Values: VST-normalized expression values
Why Parquet?
Parquet format provides:
- ~3x smaller file size than CSV
- ~10-100x faster loading times
- Native pandas support
