What is Sequana ?

Sequana is a versatile tool that provides

  1. A Python library dedicated to NGS analysis (e.g., tools to visualise standard NGS formats).
  2. A set of pipelines dedicated to NGS in the form of Snakefiles (Makefile-like with Python syntax based on snakemake framework) with more than 80 re-usable rules (see Rules).
  3. Original tools to help in the creation of such pipelines including HTML reports.
  4. Standalone applications:
    1. sequana_coverage ease the extraction of genomic regions of interest and genome coverage information
    2. sequana_taxonomy performs a quick taxonomy of your FastQ. This requires dedicated databases to be downloaded.
    3. Sequanix: GUI for snakemake workflows, a GUI for Snakemake workflows (hence Sequana pipelines as well)

Currently, the available pipelines cover quality control (e.g. adapters removal, phix removal, trimming of bad quality bases), variant calling, characterisation of the genome coverage, taxonomic classification, de-novo assembly, RNA-seq. See the Pipelines section for more information.

Sequana can be used by developers to create new pipelines and by users in the form of applications ready for production. Moreover, Sequanix can be used to set the parameters of pipelines and execute them easily with a graphical user interface.
