# Cetane Number and YSI Predictor ⛽

Predict cetane numbers from SMILES strings using machine learning.

## Features

- 🔬 **Single Prediction**: Enter one SMILES string to get instant cetane number prediction
- 📊 **Batch Prediction**: Upload CSV files with multiple SMILES for bulk predictions
- 📈 **Visual Analysis**: View molecular structures and prediction distributions
- 📥 **Export Results**: Download predictions as CSV

## How to Use

### Single Prediction
1. Go to the "Single Prediction" tab
2. Enter a SMILES string (e.g., `CCCCCCCCCCCCCCCC`)
3. Click "Predict"
4. View your Cetane Number and YSI prediction!

### Batch Prediction
1. Go to the "Batch Prediction" tab
2. Upload a CSV file with a `SMILES` column
3. Click "Predict All"
4. Download results with predictions
