And I made the model based on AC mode data (<span style="margin: 0px; padding: 0px; border: 0px; vertical-align: baseline; font-family: 'Courier New'; font-size: 10pt;">range centred around zero</span>). Now I want to analyze on-line EEG data by my previous model. But the online data is acquired in DC mode (value is big and not <span style="margin: 0px; padding: 0px; border: 0px; vertical-align: baseline; font-family: 'Courier New'; font-size: 13.3333px;">centred around zero</span>) by access SDK. I don't know how to convert DC mode data into AC mode data so that I can apply the previous model into the data?</font></div><div style="margin: 0px; padding: 0px; border: 0px; vertical-align: baseline; color: rgb(34, 34, 34); font-family: Arial, Helvetica, sans-serif; font-size: 13px; line-height: normal; widows: 1;"><font color="#000000" style="margin: 0px; padding: 0px; border: 0px; vertical-align: baseline;"><br></font></div><div style="margin: 0px; padding: 0px; border: 0px; vertical-align: baseline; color: rgb(34, 34, 34); font-family: Arial, Helvetica, sans-serif; font-size: 13px; line-height: normal; widows: 1;"><font color="#000000" style="margin: 0px; padding: 0px; border: 0px; vertical-align: baseline;">Thank you.</font></div><div style="margin: 0px; padding: 0px; border: 0px; vertical-align: baseline; color: rgb(34, 34, 34); font-family: Arial, Helvetica, sans-serif; font-size: 13px; line-height: normal; widows: 1;"><font color="#000000" style="margin: 0px; padding: 0px; border: 0px; vertical-align: baseline;">Booer</font></div></div>
