Basic Usage

from openperturbation import OpenPerturbationPipeline
from omegaconf import DictConfig

# Configure your analysis
config = DictConfig({
    "data": {
        "data_dir": "path/to/your/data",
        "batch_size": 32
    },
    "model": {
        "model_type": "multimodal_fusion",

    },
    "experiment": {
        "name": "my_perturbation_analysis",

# Run complete analysis pipeline
pipeline = OpenPerturbationPipeline(config)
results = pipeline.run_full_pipeline()

# Access results
print(f"Training completed with validation loss: {results['training']['best_val_loss']}")
print(f"Discovered {results['causal_discovery']['n_edges']} causal relationships")

OpenAI Agents Interface

from openperturbation.agents import create_openperturbation_agent
import asyncio

# Create an AI agent for interactive analysis

async def analyze_data():
    response = await agent.process_message(
        "Run causal discovery analysis on my single-cell dataset and explain the key findings"
    )
    print(response)

asyncio.run(analyze_data())
