Load epochs and add them to a dataset as
rejectargument is specified,
dsis modified in place. With
reject, a subset of
dsis returned containing only those events for which data was loaded.
ds (Dataset) – Dataset containing a variable which defines epoch cues (i_start) and to which the epochs are added.
tmin (scalar) – First sample to include in the epochs in seconds (Default is -0.1).
tmax (scalar) – Last sample to include in the epochs in seconds (Default 0.6; use
tstopinstead to specify index exclusive of last sample).
baseline ((float, float) | None) – Time interval for baseline correction.
(tmin, tmax)tuple in seconds, or
Noneto use all the data (e.g.,
(None, 0)uses all the data from the beginning of the epoch up to
t = 0). Set to
Nonefor no baseline correction (default).
decim (int) – Downsample the data by this factor when importing.
1means no downsampling. Note that this function does not low-pass filter the data. The data is downsampled by picking out every n-th sample (see Wikipedia).
mult (scalar) – multiply all data by a constant.
proj (bool) – mne.Epochs kwarg (subtract projections when loading data)
data ('eeg' | 'mag' | 'grad') – Which data channels data to include (default based on channels in data).
reject (None | scalar) – Threshold for rejecting epochs (peak to peak). Requires a for of mne-python which implements the Epochs.model[‘index’] variable.
info (None | dict) – Entries for the ndvar’s info dict.
name (str) – name for the new NDVar.
raw (None | mne Raw) – Raw file providing the data; if
sensors (None | Sensor) – The default (
None) reads the sensor locations from the fiff file. If the fiff file contains incorrect sensor locations, a different Sensor instance can be supplied through this kwarg.
i_start (str) – name of the variable containing the index of the events.
sysname (str) – Name of the sensor system to load sensor connectivity (e.g. ‘neuromag’, inferred automatically for KIT data converted with a recent version of MNE-Python).
tstop (scalar) – Alternative to
tmaxspecifies the last samples to include,
tstopcan be used to specify the epoch time excluding the last time point (i.e., standard Python/Eelbrain indexing convention). For example, at 100 Hz the epoch with
tmin=-0.1, tmax=0.4will have 51 samples, while the epoch specified with
tmin=-0.1, tstop=0.4will have 50 samples.
ds – Dataset containing the epochs. If no events are rejected,
dsis the same object as the input
dsargument, otherwise a copy of it.
