A Bayesian optimization framework for multimodal registration of highly multiplexed single-cell spatial proteomics data

Twocan

A Bayesian optimization framework for multimodal registration of highly multiplexed single-cell spatial proteomics data

Overview

Twocan automatically finds optimal parameters for registering images from different spatial proteomics technologies using Bayesian optimization. Instead of manually tuning preprocessing and registration parameters, Twocan efficiently explores the parameter space to find the best registration for your data.

Key Features:

• 🔧 Automated parameter optimization for image registration
• 🧠 Bayesian optimization via Optuna for efficient search
• 🔬 Support for multiple spatial proteomics modalities (IF, IMC, FISH, IMS)
• 📊 Built-in quality metrics and visualization tools
• 🎯 Extensible framework for custom objectives and preprocessors

Quick Start

Installation

# Install from PyPI
pip install twocan

# Or install from source
git clone https://github.com/camlab-bioml/twocan.git
cd twocan
pip install .

Basic Usage

import twocan as tc

# Load your images
moving_img = tc.read_image("moving.tif") 
fixed_img = tc.read_image("fixed.tif")

# Create estimator and optimize
estimator = tc.RegEstimator(moving_img, fixed_img)
study = estimator.optimize(n_trials=100)

# Get best transformation
best_transform = tc.pick_best_registration(study)
