# 🧬 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.
