Hi Robert,
Python package 'nsrr' (NSRR Cloud - https://github.com/nsrr/nsrr-cloud ) is built to support sleep researchers who are AWS cloud users only. For now, we have only this supported capability for python developers. To get started with NSRR Cloud, please refer to https://nsrr.github.io/nsrr-cloud/. Currently only CFS dataset is hosted in NSRR Cloud. And, we are actively working to add support for additional datasets in NSRR Cloud.
For any development environment other than AWS, we recommend users to utilize original Ruby gem (https://github.com/nsrr/nsrr-gem). First, you would have to go to https://sleepdata.org to identify MESA study folder strcuture and file naming for EDF's . Now use the following options in ruby command:
Let us know if you need any other help.
