Multichannel Systems NeuroExplorer - Manual (Page 44)

2.1.4. Markers
Marker data type in NeuroExplorer is used to represent the series of timestamps recorded from
external devices (for example, stimulation times recorded as pulses produced by the stimulus
generator) together with other stimulus or trial information.
Event data type stores only the times
when the external events occurred.
NeuroExplorer creates Marker variables when it imports strobed events from Plexon data files, when
it imports Trial Descriptor Records from the Datawave files and when DIO events with flags are
loaded from Alpha Omega files.
Viewers
You can view both the marker timestamps and additional marker information in the Markers tab of the
Data window:
Extracting Events
Usually you will need to extract events with specific trial information from the marker variables. To do
this, use Marker | Split... and Marker | Extract... menu commands.
For example, you may want to extract from the marker variable shown in the figure above only the
markers with DIOValue 131 or 132. Marker | Extract... menu command will open the Extract dialog
box in which you can specify multiple criteria for extracting events from the marker variable:
