Problems with NeuroRT dry sensor driver with DSI-24 device

Post by aizmeng »

Is this a bug about A1 channel lost with the NeuroRT Driver Collection[Wearable Sensing Dry Sensor Interface]?

Openvibe v1.2.2 was used. I used NeuroRT Driver Collection[Wearable Sensing Dry Sensor Interface] as the driver and the wearable sensing' DSI-24 device was used as EEG device.
The DSI-24 device can be connected to the Openvibe Acquisition Server. However, for the designer part, some channel data can be seen by using signal-display.xml and the A1 channel was lost.
For DSI-24, there are 24 channels,including P3,C3,F3,Fz,F4,C4,P4,Cz,Pz,A1,Fp1,Fp2,T3,T5,O1,O2,X3,X2,F7,F8,X1,A2,T6,T4.
The obtained EEG signals does not contain the A1 channel, someone can help me?

Dear aizmeng,

We were not reported this bug, but this driver was not tested with a DSI-24, since we support DSI-7.

A1 seems like an auxiliary channel, that may not be active by default, you should try to check option "Acquire Auxiliary Channel".

Also note that in "Cap montage" you should choose the "Let the driver decide" montage rather than "Custom electrode montage", otherwise your channel names will be overwritten.

Hope this helps, regards,

Thanks for your reply. However, the A1 channel is not an auxiliary channel, just a reference channel located the earlobe.
In OpenVibe v1.2.2, there is no "Cap montage" configuration item, just the Aquisition Server Configuration---Drift Correction including the "Let the driver decide".

Same to me, I try to use 'NeuroRT Collection: Wearable Sensing DSI' in acq server in openvibe to acquire signals from DSI-24 device. However, i can only get 23 channels as 'A1' channel is missing, Is there any solution ?
