How to obtain onset times of deconvolved events?

[generalciao]

I believe the deconvolved signal consists of events with a typical rise and decay and variable amplitude? How can I obtain the onset times of all events that underlie the deconvolved signal? It seems to be this likely is determined as part of the deconvolution process, but I don't see these data exposed in the output parameters. Any help would be appreciated - thank you.
