pyEGA uses the EGA REST API to download authorized datasets and files and is an alternaive to the supplied EgaDemoClient.jar REQUIREMENTS Python "requests" module http://docs.python-requests.org/en/master/ pip3 install requests First, store your credentials in ~/.ega.json: { "username": "my.email@university.edu", "password": "SuperSecurePasswordIncludes123", "key": "symmetric_encryption_key" } Your username and password are provided to you by EGA. The symmetric encryption key can be any non-empty value and is used to encrypt the data before it is transferred over the wire. You will still need to decrypt using EgaDemoClient.java If you know the stable identifier of a dataset (EGAD...) or file (EGAF...) you can fetch it directly with the "fetch" subcommand. Other commands to look at specific requests or file details are available. These would mostly apply to aborted downloads, etc., as the "fetch" command executes a complete (make request -> list request [metadata] -> download request) workflow automatically. The "fetch" command will also save a copy of the request metadata as <requestlabelid>.json TODO Download metadata package List metadata when listing authorized datasets Verify file size and MD5 hash after download Parallel download streams BUGS Files will be overwritten without warning! pyEGA version 1.0.0 James S.
