uuid

string

The id of this record.

ownerId

string

The id of the user this record belongs to. It is a GUID, it is not the EmotivID of the user.

applicationId

string

The id of the application that created this record.

applicationVersion

string

The version of the application that created this record.

title

string

The title of this record.

endDatetime

string (ISO datetime)

When this record was stopped.

licenseId

string

licenseScope

List of the data streams the license has access to.

The scope "eeg" gives access to the raw EEG data.

The scope "pm" gives access to the 2 hertz performance metrics.

subject

object

This object has a single field "subjectName". It is the subject name used to create this record. You can use querySubjects to get more information about the subject. If the record was created without a subject name, then the field "subjectName" contains the EmotivID of the user.

localOnly

boolean

If true then this record will not be uploaded to the EMOTIV cloud.

If false then it will be uploaded.

headbandPosition

string

If the headset is an EPOC X, then this field tells you the position of the headband of this headset during this record. Can be "back" or "top". If the headset is not an EPOC X, then this field is null. See updateHeadsetCustomInfo for details.

This field was added in Cortex 2.4

Depending on how you get the record, it may contains an additional field for the markers:

Name

markers

array of objects

Description

syncStatus

object

contain information of sync status (status field) and/or uploading/downloading progress (percent field).

Available values for status:

  • "pending": the record is waiting for being downloaded.

  • "downloading": the record's data is being downloaded. Check progress in percent field.

  • "downloaded": the record's data is on both the Emotiv Cloud and the local machine.

  • "notDownloaded": the record's data is on the Emotiv Cloud and not on the local machine.

  • "failedEncryption", "failedDownload": sync status of the record if requestToDownloadRecordData fails.

  • "notUploaded": the record is not uploaded to the Emotiv Cloud yet.

  • "uploading": the record is being uploaded to the Emotiv Cloud. Check progress in percent field.

  • "uploaded": the record is on both the Emotiv Cloud and the local machine.

  • "failedAccessFile", "failedDecryption", "failedUpload": sync status of the record whose uploading fails. Cortex will try uploading again.

  • "neverUploaded": The record will never be uploaded to the Emotiv Cloud. The record is created with virtual headsets in this case.

For example:

  • A record is created but waiting for being uploaded to the Emotiv Cloud:

{
    "status": "notUpload"
}
  • A record is waiting for downloaded from the Emotiv Cloud:

{
    "status": "pending"
}
  • A record is created and is uploading to the Emotiv Cloud:

{
    "status": "uploading",
    "percent": 30
}
