mne.epochs.combine_event_ids(epochs, old_event_ids, new_event_id, copy=True)[source]¶ Collapse event_ids from an epochs instance into a new event_id.
- Parameters
- epochsinstance of
Epochs The epochs to operate on.
- old_event_ids
str, orlist Conditions to collapse together.
- new_event_id
dict, orint A one-element dict (or a single integer) for the new condition. Note that for safety, this cannot be any existing id (in epochs.event_id.values()).
- copybool
Whether to return a new instance or modify in place.
- epochsinstance of
Notes
This For example (if epochs.event_id was {‘Left’: 1, ‘Right’: 2}:
combine_event_ids(epochs, [‘Left’, ‘Right’], {‘Directional’: 12})
would create a ‘Directional’ entry in epochs.event_id replacing ‘Left’ and ‘Right’ (combining their trials).
