Hi,

The source is searched in the Event table. There must be an event which matches with the time range of your signal. Are you recording with a pre-trigger, a usual good practice? I checked in the source code.: if the source time is not included in the recording range, the source is not identified. There is an option to specified a minimum velocity and extend the search before the recording range. It is currently not used and I can't remember why. This should be investigated. Can you submit a file example?

Best regards,

Marc
