MneExperiment.fix_events(ds)

Modify event order or timing

Parameters

ds (Dataset) – A Dataset containing events (with variables as returned by load.fiff.events()).

Returns

ds – Should return the modified events dataset. Needs to contain at least the i_start and trigger columns.

Return type

label_events

Add event labels

Notes

Override this method in subclasses to change the event structure or timing. This method is called before adding other variables.

The subject and session the events are from can be determined with ds.info['subject'] and ds.info['session'].

Calling the original (super-class) method is not necessary.

Examples

Drop the last event from subject S01:

class Experiment(MneExperiment):

    def fix_events(self, ds):
        if ds.info['subject'] == 'S01':
            return ds[:-1]
        else:
            return ds
