Starting a notebook

Either form the Launcher (menubar File -> New Launcher) or from the menubar File -> New -> Notebook. For more information see the main JupyterLab documentation.

Processes stop running when you logout from the system. In order to have scripts running for longer see Long Running Processes.

Directory paths

• Your home directory in Jupyterlab is /home/username

• Your data storage is /storage/username

• Your shared storage is in /home/username/Shared (use this to share notebooks with other users as everyone can see this).

• Tutorials will go to /home/username/Tutorials

where username is your archive username.

Please keep your home directory for notebooks and your data storage for data.

Notebook backups

Your last 10 saved notebooks are backed up in the same directory as your notebook with name .notebook_name.py*. You can access those from the terminal window.

Copy data

Use sftp: sftp -P 2222 username@imaxt.ast.cam.ac.uk. After authentication you can access /home/username and /storage/username. For more information follow Using SSH or SFTP [Deprecated].

You can start RStudio in two ways:

• Select RStudio in the Launcher (File -> New Launcher).
