The MDB Web Interface uses the Curator DB as the backend to allow scientists The MDB Web Interface uses the Curator DB as the backend to allow scientists

to see and interact with the experiment metadata in a user-friendly wayto see and interact with the experiment metadata in a user-friendly way

The Analysis web service is a part of the Interface that lets users generate The Analysis web service is a part of the Interface that lets users generate

analysis figures from pre-existing data on the fly; they can then view and analysis figures from pre-existing data on the fly; they can then view and

download the figures through the interface.download the figures through the interface.
