ExonSurfer is a web-based tool for designing high-specific transcript primers, built with Django and powered by the ExonSurfer python package. This tool enables users to customize search options, visualize results, and obtain primers with high specificity and minimal non-specific binding. Designed for user-friendliness, speed, and accuracy, ExonSurfer integrates automated workflows to streamline the primer design process.

• Python 3
• Docker or Docker-podman
• The ExonSurfer python package
• PyEnsembl

1. Clone the ExonSurfer repository to your local machine:

   git clone https://github.com/pamonlan/ExonSurferWeb.git

2. Install the required dependencies using pip:

   pip install -r requirements.txt

3. Start the service using Docker or Docker-podman with the provided docker-compose.prod.yml file:

   docker-compose -f docker-compose.prod.yml up -d

   or

   podman-compose -f docker-compose.prod.yml up -d

4. Access the web tool through a web browser at http://localhost:8889.

• Ensembl Database: The web tool utilizes the Ensembl database via the PyEnsembl API for accurate and up-to-date genomic data. To set up, run the following in the entrypoint.sh script:

  pyensembl install --release 108 --species homo_sapiens

• BLAST Database: Primers are verified using a BLAST search to ensure specificity. The BLAST database is automatically set up using exonsurfer.py during the Docker container initialization.

• Zenodo Downloads: Additional resources and datasets are downloaded from Zenodo as part of the initialization process to ensure all necessary data is available for primer design.

• Primer design is performed by executing exonsurfer.py, with task queuing managed via Django RQ to handle background processing efficiently.
