+# 🧬 GBM Survival Gene Expression Dataset
+
+This dataset contains large-scale gene expression data (RNA-Seq and Microarray) curated for predicting the survival outcomes of patients with Glioblastoma Multiforme (GBM) and Lower-Grade Glioma (LGG).
+
+It is specifically designed to be used with the [GBM Survival Mamba](https://github.com/congkx123789/Tin_sinh_h-c) project.
+
+## 📂 Data Structure
+
+The data is organized into three main phases:
+
+### 1. `01_raw/` (Raw Data)
+Untouched genomic data from international portals:
+- **TCGA**: RNA-Seq data from The Cancer Genome Atlas (USA).
+- **CGGA**: Chinese Glioma Genome Atlas data (Asia).
+- **GEO**: Various cohorts from NCBI Gene Expression Omnibus (REMBRANDT, GSE4412, etc.).
+
+### 2. `02_processed/` (Cleaned & Normalized)
+Ready-to-use data for machine learning:
+- **training/**: Internal Train/Val/Test splits used for model development.
+- **validation/**: External independent cohorts for performance verification.
+- Files include `X.csv` (feature matrices with 16,383 genes) and `y.csv` (survival time and status).
+
+### 3. `03_metadata/`
+Mapping tables between Gene Symbols and Probe IDs, as well as clinical metadata.
+
+## 🚀 How to use with the Project
+
+If you have cloned the [GitHub repository](https://github.com/congkx123789/Tin_sinh_h-c), you can automatically sync this data by running:
+
+```bash
+python scripts/download_data_hf.py
+```
+
+This will download all files and place them in the correct `data/` directory structure.
