For Workshop members without access to computing resources - Preconfigured Amazon Web Services servers can be used
Accessing compute resources on AWS:
Speak with Jeff Stout to get the current IP address and PEM key
chmod 400 AWS.pem
${PATH} is the path to the PEM key provided to you
ssh -X -i AWS.pem user1@ec2-3-230-155-59.compute-1.amazonaws.com
Windows Laptops do not have X11 installed natively. Download an Xterm software for visualization.
MobaXterm has been tested to work: https://mobaxterm.mobatek.net/download.html
Jupyter Notebook Over a Remote Connection
1) Run one terminal to start the notebook and forward the outputs to local web browser:
ssh -i AWS.pem -L 8887:localhost:8887 ubuntu@IP_ADDRESS conda activate workshop jupyter notebook --no-browser --port=8887
2) Copy the output of the jupyter notebook command (see example below) and enter into your laptop web browser (Firefox, Chrome, etc.). Do not click on the link - it will try to launch on the AWS computer
3) Use the jupyter notebook to analyze MEG data with python tools
