🧬 DeepChopper leverages language model to accurately detect and chop artificial sequences which may cause chimeric reads, ensuring higher quality and more reliable sequencing results. By integrating seamlessly with existing workflows, DeepChopper provides a robust solution for researchers and bioinformatics working with NanoPore direct-RNA sequencing data.

🚀 Quick Start: Try DeepChopper Online

Experience DeepChopper instantly through our user-friendly web interface. No installation required! Simply click the button below to launch the web application and start exploring DeepChopper's capabilities:

What you can do online:

• 📤 Upload your sequencing data
• 🔬 Run DeepChopper's analysis
• 📊 Visualize results
• 🎛️ Experiment with different parameters

Perfect for quick tests or demonstrations! However, for extensive analyses or custom workflows, we recommend installing DeepChopper locally.

⚠️ Note: The online version is limited to one FASTQ record at a time and may not be suitable for large-scale projects.

📦 Installation

DeepChopper can be installed using pip, the Python package installer. Follow these steps to install:

1. Ensure you have Python 3.10 or later installed on your system.

2. Create a virtual environment (recommended):

   python -m venv deepchopper_env
   source deepchopper_env/bin/activate  # On Windows use `deepchopper_env\Scripts\activate`

3. Install DeepChopper:

   pip install deepchopper

4. Verify the installation:

   deepchopper --help

🛠️ Usage

For a comprehensive guide, check out our full tutorial. Here's a quick overview:

Command-Line Interface

DeepChopper offers three main commands: encode, predict, and chop.

1. Encode your input data:

   deepchopper encode <input.fq>

2. Predict chimera artifacts:

   deepchopper predict <input.parquet> --output predictions

   Using GPUs? Add the --gpus flag:

   deepchopper predict <input.parquet> --output predictions --gpus 2

3. Chop chimera artifacts:

   deepchopper chop <predictions> raw.fq
