align¶

Align spikes or continuous signals to event times. Works with ragged spikes, binned spikes, or continuous signals.

Example¶

aligned = da.ephys.align(events=events, to="go_cue", window=(-0.5, 1.0))

Notes¶

events can be a DataArray with dims (trial, event, bound) or (trial, event). The "start" bound is used by default.
events can also be 1D array-like event times; in that case to is optional.
The output keeps compatible trial/unit coordinates and updates ephys.valid_intervals.

NumPy input¶

from aind_ephys_utils.ops import align

aligned = align(
    spikes,               # list[np.ndarray], one array per unit
    events=event_times,   # 1D array-like, one event time per trial
    window=(-0.5, 1.0),
)

Common patterns¶

Align to a different event:

aligned = da.ephys.align(events=events, to="reward", window=(-0.2, 0.8))
