  • The ECoghG area under the curve graph is now a property of the recording and can be activated for the individual recording from the right-click menu or the recording information panel

Changes as of version 5.54.10:

  • When placing a label the latency and amplitude marker will now move simultaneously while using the right/left arrow keys when they are at the same position. If the markers are at different positions, only the latency marker will move.
  • The Stimulus Tab in the Recording Information panel now shows the stimulus window information.
  • The recording information submenu (right-click on a waveform) now shows the impedance information for each electrode as A-, A+, Gnd, B+, and B-).
