Parameters: |
- raw : Raw object
The raw data.
- pad_start: None | int
Values to assume outside of the stim channel (e.g., if pad_start=0 and
the stim channel starts with value 5, an event of [0, 0, 5] will be
inserted at the beginning). With None, no steps will be inserted.
- pad_stop : None | int
Values to assume outside of the stim channel, see pad_start .
- merge : int
Merge steps occurring in neighboring samples. The integer value
indicates over how many samples events should be merged, and the sign
indicates in which direction they should be merged (negative means
towards the earlier event, positive towards the later event).
- stim_channel : None | string | list of string
Name of the stim channel or all the stim channels
affected by the trigger. If None, the config variables
‘MNE_STIM_CHANNEL’, ‘MNE_STIM_CHANNEL_1’, ‘MNE_STIM_CHANNEL_2’,
etc. are read. If these are not found, it will default to
‘STI101’ or ‘STI 014’, whichever is present.

Returns: |
- steps : array, shape = (n_samples, 3)
For each step in the stim channel the values [sample, v_from, v_to].
The first column contains the event time in samples (the first sample
with the new value). The second column contains the stim channel value
before the step, and the third column contains value after the step.
