Quick Guide
  • Click a source to select it; drag to move.
  • Drag the arrowhead to rotate dipoles.
  • Use Y slider to move sources anterior/posterior.
  • Keyboard: Delete removes; A/D rotate; W/S amplitude.
  • Upload CSV: time,ch1,ch2,... format.
Reference Designs
  • Average Reference: Software subtraction of mean of all electrodes.
  • Design 1 (CMS/DRL): Dedicated CMS electrode captures common mode directly. All electrodes referenced to CMS. DRL integrates CMS signal and injects back.
  • Design 2 (Ref/CMS/DRL): Reference electrode for signal. Virtual CMS computed by averaging all electrode values in hardware. DRL injects averaged signal.
