- mne.time_frequency.tfr_stockwell(inst, fmin=None, fmax=None, n_fft=None, width=1.0, decim=1, return_itc=False, n_jobs=None, verbose=None)[source]#
Compute Time-Frequency Representation (TFR) using Stockwell Transform.
Same computation as
tfr_array_stockwell
, but operates onEpochs
objects instead ofNumPy arrays
.See [1][2][3][4] for more information.
- Parameters:
- inst
Epochs
|Evoked
The epochs or evoked object.
- fmin
None
,float
The minimum frequency to include. If None defaults to the minimum fft frequency greater than zero.
- fmax
None
,float
The maximum frequency to include. If None defaults to the maximum fft.
- n_fft
int
|None
The length of the windows used for FFT. If None, it defaults to the next power of 2 larger than the signal length.
- width
float
The width of the Gaussian window. If < 1, increased temporal resolution, if > 1, increased frequency resolution. Defaults to 1. (classical S-Transform).
- decim
int
The decimation factor on the time axis. To reduce memory usage.
- return_itc
bool
Return intertrial coherence (ITC) as well as averaged power.
- n_jobs
int
The number of jobs to run in parallel (over channels).
- verbose
bool
|str
|int
|None
Control verbosity of the logging output. If
None
, use the default verbosity level. See the logging documentation andmne.verbose()
for details. Should only be passed as a keyword argument.
- inst
- Returns:
- power
AverageTFR
The averaged power.
- itc
AverageTFR
The intertrial coherence. Only returned if return_itc is True.
- power
