Setup

• If possible, we do recommend using the Remote option over Local ( Especially for Windows hosts). This will eliminate the need to install any additional applications

• Remote option will require an existing NeSI Account

Remote

Log into NeSI Mahuika Jupyter Service - Not required if the workshop is running on OpenOnDemand based Training environment

1. Follow https://jupyter.nesi.org.nz/hub/login

2. Enter NeSI username, HPC password and 6 digit second factor token
   

3. Choose server options as below
   >>make sure to choose the correct project code nesi02659, number of CPUs CPUs=2, memory 4 GB prior to pressing button.

Local

Local host setup - Windows, MacOS & Linux

Windows HostsMacOSLinux

• Install either
• Git for Windows from https://git-scm.com/download/win OR
• MobaXterm Home (Portable or Installer edition) from https://mobaxterm.mobatek.net/download-home-edition.html
  • Portable edition does not require administrative privileges

• Native terminal client is sufficient.
• It might not comes with wget download data via command line (can be installed with $ brew install wget)
• However, it is not required as we provide a direct link to download data in .zip format

• Native terminal client is sufficient.

bioawk install on all hosts

One of the tools used in this workshop is bioawk which is not a native Linu/UNIX utility. Installing it on MacOS and Linux can be done with $ brew install bioawk & $ sudo apt install bioawk, respectively. Windows hosts might have to do it via conda according to these instructions. However, this will require a prior install of Anaconda Or Miniconda
