After you opened a session with a headset, you can create a record. A record is a permanent object to store data from an EMOTIV headset. You can associate a subject to a record. You can add one or more markers to a record.
Unlike a session, a record is a permanent object. It is stored on the hard drive and then can be synchronized to the EMOTIV cloud. The opt-out configuration can let you decide if the records of a user are uploaded to the cloud or not.
