🎟️ nf-raffle

This repository contains code for the nf-raffle pipeline, which is used for managing raffles at events attended or sponsored by Seqera.

Description

nf-raffle is a Nextflow pipeline designed to streamline the process of entering raffles at various events. It provides a simple and efficient way to collect participant information and enter them into event-specific raffles.

Supported Events

Currently, the pipeline supports the following events:

• SLAS 2025 [--event slas_2025]
• ISMB 2025 [--event ismb_2025]
• BiotechX 2025 [--event biotechx_2025]
• ASHG 2025 [--event ashg_2025] (default)

How to Run

There are two ways to run the raffle:

• From Seqera Platform at the booth. Come talk to us!
• From the Nextflow command line on your laptop (see below)

Overview

The nf-raffle pipeline guides you through an interactive raffle entry process where you'll provide your contact information and be entered into the event raffle. The pipeline uses Nextflow and integrates with Seqera Platform for enhanced functionality.

If you are already familiar with Nextflow, you can enter the raffle the following way:

1. Ensure you have a Seqera Platform access token set as TOWER_ACCESS_TOKEN in your environment.
2. Run the Nextflow pipeline seqeralabs/nf-raffle
3. (Optional) Add --event [event_name] to specify one of the supported events (defaults to ashg_2025 if not specified).

Below are detailed instructions for new users.

Step 1: Install Nextflow

First, ensure you have Java 11 or later installed, then install Nextflow:

# Install Nextflow
curl -s https://get.nextflow.io | bash

# Make it executable and move to your PATH
chmod +x nextflow
sudo mv nextflow /usr/local/bin/

Verify the installation:

nextflow -version

You should see something like this:

>  nextflow -version

2. Sign up for a free account or sign in with your existing credentials
3. Complete the account verification process

Step 3: Generate an Access Token

1. Navigate to Your profile → Access tokens in the Seqera Platform
2. Click New token
3. Provide a name for your token (e.g., "nf-raffle-token")
4. Click Create and copy the generated token

Step 4: Set Environment Variable

Set your access token as an environment variable:

export TOWER_ACCESS_TOKEN=your_token_here
