bidsaid.events.PresentationBlockExtractor.extract_onsets

PresentationBlockExtractor.extract_onsets(scanner_start_time=None)

Extract the onset times for each event.

Onset is calculated as the difference between the event time and the scanner start time (e.g. first pulse).

Parameters

scanner_start_timefloat, int, or None, default=None

The start time for the scanner.

Important

Scanner start time will be detected during class initialization, unless the self.scanner_event_code and self.scanner_trigger_code does not return an index.

Returns

list[float]

A list of onset times for each block.
