Recording

Record data in real time to EDF (BDF+) or CSV by selecting Record on the Visualization page.

A pop-up will allow you to configure your recording.

Settings include:

File format – select the output file type (EDF or CSV):
- CSV mode generates an extra file for the marker events
- BDF mode records data in BDF+ format (in 24-bit resolution)
Folder and name prefix – select where to store files and the file prefix. For example, if the prefix is test, data will record in three separate files: test_ExG.csv, test_ORN.csv, and test_Marker.csv. These files will contain ExG data, orientation data, and event markers.
Recording time (in seconds) – set the duration of the recording. You can stop recording at any time by clicking Stop.- Filters.

You can inspect ongoing recording while recording. Go to Tools-> Inspect ongoing recording. Then zoom in/out with mouse hover on X or Y axis

Because environmental factors, like temperature, can affect your sampling rate, we recommend computing the sampling rate of your recorded data. If you find a deviation between the sampling rate you calculate and Explore Desktop’s sampling rate, resample your signal to correct for drifts. The timestamps in the CSV/EDF file can be used to compute the resampling factor.

If you are setting markers in your recording, record to CSV. Alternatively, push data to LSL and record with LabRecorder. EDF cannot guarantee precise marker timings.

Event markers

One method to generate a marker event is to press the button on your Mentalab Explore device. Alternatively, you can set event markers using the Set Marker button.

Marker events display as red vertical lines in the visualization page. A corresponding event code will be shown next to the line.
