How to get CMS value.

Hi all,

Using speed mode 4, the # of channels is 256 @ 2048Hz.
Can i get CMS(DRL) value from ring-buffer?
I have tried to make display module like 'Electrode Offset' tab in Actiview.

Best regards
Kei

Thanks for your response, Coen.

May i ask how to calculate 'electrode offset' value in Actiview module?

Thanks in advance for your help!

The offsets displayed in ActiView are simply the DC (better: low frequency) values of the unreferenced channels. For example, take the average value across intervals of a second or so. More info is found at: viewtopic.php?t=56 .
