Metagenomics Summer School

Course materials for the Genomics Aotearoa Metagenomics Summer School, to be hosted at the University of Auckland in November.

A draft timetable for the day is provided below, but please keep in mind that this is subject to change as we evaluate our course material.

Useful locations and links

Working directories

For all exercises after the bash introduction, you will be working from the file path

/nesi/nobackup/nesi02659/MGSS_U/YOUR_USERNAME/

bash/slurm cheatsheet

A few helpful commands and shortcuts for working in bash or with slurm can be found here.

Snapshots of results to download

If you are having trouble downloading files using scp, we are providing exemplar output files, which you can download through your browser, here, or via the following links:

Slides for workshop

You can find a copy of the slides presented during the workshop, with published figures removed, in the slides/ folder.

Etherpad

We will be using a collaborative document to share long code, results, or even code errors. This document can be found here or type https://etherpad.wikimedia.org/p/MGSS_17_11_20 in your browser.
