1 - Nectar Virtual Desktop Service

There are a few differences between the open-source version of Neurodesk and what’s hosted on Nectar VDI:

1. There is no /neurodesktop-storage folder (the folder on the Desktop does not lead anywhere).
2. Files uploaded via drag and drop do not get stored on the desktop but in /home/vdiuser/thinclient_drives/GUACFS

Instructions for use

1. Go to https://desktop.rc.nectar.org.au/

2. Click on “Sign in”.

3. Choose the AAF option.

4. Choose your institution from the list.

5. Provide your email address and password.

6. Click on create a Workspace (you only need to do this when you sign in for the first time).

7. Fill form ‘Apply for new Workspace’ and submit.

8. Click on “EXPLORE”.

9. Click “VIEW DETAILS” under Neurodesktop:

10. Click “CREATE DESKTOP +” button on the top right corner.

11. Choose the desired availability zone.

12. Wait until everything is completed:

13. Click “OPEN DESKTOP ->”:

3 - Google Colab

Open a notebook in Google Colab and run the following commands to set up the Neurodesk environment:

import os
os.environ["LD_PRELOAD"] = "";
os.environ["APPTAINER_BINDPATH"] = "/content"
os.environ["MPLCONFIGDIR"] = "/content/matplotlib-mpldir"
os.environ["LMOD_CMD"] = "/usr/share/lmod/lmod/libexec/lmod"

!curl -J -O https://raw.githubusercontent.com/NeuroDesk/neurocommand/main/googlecolab_setup.sh
!chmod +x googlecolab_setup.sh
!./googlecolab_setup.sh

os.environ["MODULEPATH"] = ':'.join(map(str, list(map(lambda x: os.path.join(os.path.abspath('/cvmfs/neurodesk.ardc.edu.au/neurodesk-modules/'), x),os.listdir('/cvmfs/neurodesk.ardc.edu.au/neurodesk-modules/')))))

Once this setup is completed you can list the available Neurodesk applications like this:

import lmod
await lmod.avail()

and use applications like this:

await lmod.load('fsl/6.0.4')
!bet
