- credentials leave this as your Imperial College identity. The guests you share this collection with will have at most the same amount of access that you do. It's not possible to give read or write access to files that you yourself don't have. When setting up the sharing later, you will have the option to further restrict guests to have read-only access.
- base directory this is the RDS path from which the sharing will start. Start it with /project/RDS project shortname/live/ All the files and folders below this point will be shared within this new collection. Don't make it broader than you need to, or you may share more than you intended. When setting up the sharing later, you have the option to further restrict access to subfolders.
- collection display name a meaningful name for the collection, this is the name used to search for the collection when setting up a file transfer
3. Click on Create Collection then "Share data on this collection with other users", then click on "Add Permissions - Share With". To complete this:
- path the folder from which to start the sharing. This is relative to the base directory you specified earlier. The default is "/" - sharing everything in the base directory and below
- username or email the person you wish to share with. This should be an institutional ID that the person can log in to Globus with.
- permissions you may grant write access for the user. Note if you can't grant write access to files or folders that you yourself can't write.
