exportRecord

This method is to export one or more records to EDF or CSV files.

You can export the raw EEG data, the motion data, the performance metrics and the band powers. The available data streams depend on the license of the record. You can check the field licenceScope in the Record object to know which data streams are available.

By default, you can only export the records that were created by your application. If you want to export a record that was created by another application (e.g. Emotiv PRO or EMOTIV LABS) then you must provide the license id of this application in the parameter licenseIds.

In order to export a record created by EMOTIV LABS, the current Cortex user must be the owner of the LABS experiment.

You must before you can export it. If you want to export a record immediately after you stop it then you must wait for the before you try to export.

The format of the exported files is described in .

This method was added in Cortex 2.1.1 to all desktop versions of Cortex. It was added to iOS and Android in Cortex 2.7.0

Parameters

Data streams

The parameter streamTypes must contain one or more values, chosen from this list: "EEG", "MOTION", "PM", "BP". If the format is "EDF" then only "EEG" and "MOTION" are available.

Format and version

Depending on the parameters format and version Cortex will create different files.

Format EDF, no version

This format is identical to the one used in Cortex 1.x

• 1 EDF file for the EEG and CQ data

• 1 EDF file for the motion data

• 1 JSON file for the markers

Format EDFPLUS/BDFPLUS, no version (available since Cortex version 3.7.5)

• 1 EDF+/BDF+ file for the EEG, CQ and Motion data

• 1 JSON file for the markers

• 1 CSV file for the markers if the parameter includeMarkerExtraInfos is true

Format CSV, version V1

This format is identical to the one used in Cortex 1.x

• 1 CSV file for the EEG and CQ data

• 1 CSV file for the band powers

• 1 CSV file for the motion data

Format CSV, version V2

This format is the new format of Cortex 2.x

• 1 CSV file for all the data streams (EEG, CQ, band powers, motion, PM)

• 1 JSON file for the markers

• 1 CSV file for the markers if the parameter includeMarkerExtraInfos is true

Result

The result is an object that includes these fields:

In case of success, you get an object with these fields:

In case of failure, you get an object with these fields:
