Learning Outcomes

By the end of this session, you will be able to:

  • Structurally and functionally annotate a eukaryotic genome assembly with EASEL using protein and RNA extrinsic evidence
  • Assess non-model genome annotation quality with BUSCO score, mono:multi-exonic ratio, and reciprocal BLAST annotation rate
  • Address challenges with accuracy and efficiency for genome annotation

Prerequisites

This tutorial will provide a walk-through of the EASEL annotation pipeline. If you're interested in running EASEL yourself, you can follow the installation instructions on the GitLab repository.

Please make sure you MEET THE PREREQUISITES and READ THE DESCRIPTION above

You will get the most out of this session if you meet the prerequisites above.

Please also read the description carefully to see if this session is relevant to you.

If you don't meet the prerequisites or change your mind based on the description or are no longer available at the session time, please email tol-training at sanger.ac.uk to cancel your slot so that someone else on the waitlist might attend.
