BLAST pipeline

This example splits a FASTA file into chunks and executes a BLAST query for each chunk in parallel. Then, all the sequences for the top hits are collected and merged into a single result file.

Try it on your computer

To run this pipeline on your computer, you will need:

Install Nextflow by entering the following command in the terminal:

$ curl -fsSL | bash

Then launch the pipeline with this command:

$ ./nextflow run blast-example -with-docker

It will automatically download the pipeline GitHub repository and the associated Docker images, thus the first execution may take a few minutes to complete depending on your network connection.

NOTE: To run this example with versions of Nextflow older than 22.04.0, you must include the -dsl2 flag with nextflow run.
