KB0029: Troubleshooting Event Mode

Events, or key points of interest in a data file, can be used in the MindWare analysis applications to define segments of analysis. These events can be read from the data file itself, read from a text-based event file, or detected from a digital pulse data channel. Below are potential questions related to using events:


 

Issue: Event mode controls are disabled

Event controls disabled

To analyze based on events in the MindWare analysis applications, you need to change the Mode setting to either Event or Event and Time. When Event mode has been selected, the event-based settings will be enabled.

Issue: Event mode cannot be selected

Event Mode Disabled

If Event  mode cannot be selected, ensure that an event file has been specified in the Event File Path field and Use BioLab Event File is checked

or a channel has been mapped as “Event” and Use BioLab Event File is unchecked

Note: MWX/MWI files contain event data within them, and thus a BioLab Event File is unnecessary. If events are present in the MWX/MWI files, the event option will be enabled automatically.

Note: Unless the data file and event file have been moved or renamed, the analysis applications will usually automatically locate and load the corresponding event file. After an event file has been loaded once, it’s path will be stored in the user preferences file for future use.


 

Issue: Only certain events are shown in the Events List

Ensure that Filter Events has not been set to only display a certain type of events. Try changing this setting to “All Events”.
