# DyneTrion: Spatiotemporally Coherent Generative Emulation of Protein Dynamics Across Timescales

This repository contains the pretrained weights for **DyneTrion**, a generative protein dynamics emulator that jointly enforces geometric symmetry, structural consistency, and temporal coherence within a single framework.

## Installation

```bash
# Create virtual environment (Python 3.10.12 is recommended)
python -m venv .venv
source .venv/bin/activate

# Install PyTorch (CUDA 12.4)
pip install torch==2.4.0 --index-url https://download.pytorch.org/whl/cu124

# Install other dependencies
pip install -r requirements.txt
```

## Inference

Run inference using:

```bash
bash inference.sh
```

- Model checkpoint: `step_400000.pth`
- Input CSV: `datasets/inference/inference_data.csv`
- Frame number: `n_frame = 16`
- Motion number: `n_motion = 2`
- Frame sampling step: `sample_step = 40`
- Extrapolation time: `extrapolation_time = 16`
- Noise scale: `noise_scale = 1.0`

Inference results will be saved to `save_root` (default: `./test/inference/`).
