# AutoMat Benchmark: STEM Image to Crystal Structure
The **AutoMat Benchmark** is a multimodal dataset designed to evaluate deep‑learning systems for iDPC-STEM‑based crystal‑structure reconstruction and property prediction.
Code: https://github.com/yyt-2378/AutoMat
---
## 📁 Dataset Structure
The dataset is organized into three tiers of increasing difficulty:
```text
benchmark/
├── tier1/
│ ├── img/ # STEM images (e.g., PNG, TIFF)
│ ├── label/ # Atomic position labels (e.g., TXT, JSON)
│ └── cif_file/ # Reconstructed or ground‑truth CIF files
├── tier2/
│ └── ... # Same sub‑folders as tier1
├── tier3/
│ └── ...
└── property.csv # Material properties for all samples
````
---
## 🔬 Tier Descriptions
| Tier | Characteristics |
|--------|----------------------------------------------------------------|
| Tier 1 | Simulated low-noise STEM images, light elements, low complexity |
| Tier 2 | Moderate noise or multiple elements, more realistic patterns |
| Tier 3 | Low dose, multi-elements, complex symmetry |
Each sample in the dataset includes:
- A STEM image (`img/`)
- Labeled atomic coordinates (`label/`)
- A reconstructed or reference CIF file (`cif_file/`)
- Associated material properties in `property.csv`
---
## 📊 Tasks Supported
- STEM-to-structure inference
- CIF generation and comparison
- Atomic position prediction
- Property prediction (formation energy, energy_per_atom, bandgap, etc.)
---
## 🔗 Files Description
| File / Folder | Description |
|--------------------|------------------------------------------------------------|
| `img/` | STEM input images (grayscale microscopy) |
| `label/` | Atomic position data (format: .png per sample) |
| `cif_file/` | .cif crystal structure files for each sample |
| `property.csv` | Global material properties table with `material_id` match |
