# Time-frequency on simulated data (Multitaper vs. Morlet vs. Stockwell vs. Hilbert)#

This example demonstrates the different time-frequency estimation methods on simulated data. It shows the time-frequency resolution trade-off and the problem of estimation variance. In addition it highlights alternative functions for generating TFRs without averaging across trials, or by operating on numpy arrays.

## Simulate data#

We’ll simulate data with a known spectro-temporal structure.

```
sfreq = 1000.0
ch_names = ["SIM0001", "SIM0002"]
ch_types = ["grad", "grad"]
info = create_info(ch_names=ch_names, sfreq=sfreq, ch_types=ch_types)
n_times = 1024 # Just over 1 second epochs
n_epochs = 40
seed = 42
rng = np.random.RandomState(seed)
data = rng.randn(len(ch_names), n_times * n_epochs + 200) # buffer
# Add a 50 Hz sinusoidal burst to the noise and ramp it.
t = np.arange(n_times, dtype=np.float64) / sfreq
signal = np.sin(np.pi * 2.0 * 50.0 * t) # 50 Hz sinusoid signal
signal[np.logical_or(t < 0.45, t > 0.55)] = 0.0 # hard windowing
on_time = np.logical_and(t >= 0.45, t <= 0.55)
signal[on_time] *= np.hanning(on_time.sum()) # ramping
data[:, 100:-100] += np.tile(signal, n_epochs) # add signal
raw = RawArray(data, info)
events = np.zeros((n_epochs, 3), dtype=int)
events[:, 0] = np.arange(n_epochs) * n_times
epochs = Epochs(
raw,
events,
dict(sin50hz=0),
tmin=0,
tmax=n_times / sfreq,
reject=dict(grad=4000),
baseline=None,
)
epochs.average().plot()

## Calculate a time-frequency representation (TFR)#

Below we’ll demonstrate the output of several TFR functions in MNE:

### Multitaper transform#

First we’ll use the multitaper method for calculating the TFR.
This creates several orthogonal tapering windows in the TFR estimation,
which reduces variance. We’ll also show some of the parameters that can be
tweaked (e.g., `time_bandwidth`

) that will result in different multitaper
properties, and thus a different TFR. You can trade time resolution or
frequency resolution or both in order to get a reduction in variance.

```
freqs = np.arange(5.0, 100.0, 3.0)
vmin, vmax = -3.0, 3.0 # Define our color limits.
fig, axs = plt.subplots(1, 3, figsize=(15, 5), sharey=True, layout="constrained")
for n_cycles, time_bandwidth, ax, title in zip(
[freqs / 2, freqs, freqs / 2], # number of cycles
[2.0, 4.0, 8.0], # time bandwidth
axs,
[
"Sim: Least smoothing, most variance",
"Sim: Less frequency smoothing,\nmore time smoothing",
"Sim: Less time smoothing,\nmore frequency smoothing",
],
):
power = epochs.compute_tfr(
method="multitaper",
freqs=freqs,
n_cycles=n_cycles,
time_bandwidth=time_bandwidth,
return_itc=False,
average=True,
)
ax.set_title(title)
# Plot results. Baseline correct based on first 100 ms.
power.plot(
[0],
baseline=(0.0, 0.1),
mode="mean",
vlim=(vmin, vmax),
axes=ax,
show=False,
colorbar=False,
)
```

### Stockwell (S) transform#

Stockwell uses a Gaussian window to balance temporal and spectral resolution.
Importantly, frequency bands are phase-normalized, hence strictly comparable
with regard to timing, and, the input signal can be recoverd from the
transform in a lossless way if we disregard numerical errors. In this case,
we control the spectral / temporal resolution by specifying different widths
of the gaussian window using the `width`

parameter.

```
fig, axs = plt.subplots(1, 3, figsize=(15, 5), sharey=True, layout="constrained")
fmin, fmax = freqs[[0, -1]]
for width, ax in zip((0.2, 0.7, 3.0), axs):
power = epochs.compute_tfr(method="stockwell", freqs=(fmin, fmax), width=width)
power.plot(
[0], baseline=(0.0, 0.1), mode="mean", axes=ax, show=False, colorbar=False
)
ax.set_title(f"Sim: Using S transform, width = {width:0.1f}")
```

```

### Morlet Wavelets#

Next, we’ll show the TFR using morlet wavelets, which are a sinusoidal wave
with a gaussian envelope. We can control the balance between spectral and
temporal resolution with the `n_cycles`

parameter, which defines the
number of cycles to include in the window.

```
fig, axs = plt.subplots(1, 3, figsize=(15, 5), sharey=True, layout="constrained")
all_n_cycles = [1, 3, freqs / 2.0]
for n_cycles, ax in zip(all_n_cycles, axs):
power = epochs.compute_tfr(
method="morlet", freqs=freqs, n_cycles=n_cycles, return_itc=False, average=True
)
power.plot(
[0],
baseline=(0.0, 0.1),

show=False,
colorbar=False,
)
n_cycles = "scaled by freqs" if not isinstance(n_cycles, int) else n_cycles
ax.set_title(f"Sim: Using Morlet wavelet, n_cycles = {n_cycles}")
```

### Narrow-bandpass Filter and Hilbert Transform#

Finally, we’ll show a time-frequency representation using a narrow bandpass filter and the Hilbert transform. Choosing the right filter parameters is important so that you isolate only one oscillation of interest, generally the width of this filter is recommended to be about 2 Hz.

```
fig, axs = plt.subplots(1, 3, figsize=(15, 5), sharey=True, layout="constrained")
bandwidths = [1.0, 2.0, 4.0]
for bandwidth, ax in zip(bandwidths, axs):
data = np.zeros(
(len(epochs), len(ch_names), freqs.size, epochs.times.size), dtype=complex
)
for idx, freq in enumerate(freqs):
# Filter raw data and re-epoch to avoid the filter being longer than
# the epoch data for low frequencies and short epochs, such as here.
raw_filter = raw.copy()
# NOTE: The bandwidths of the filters are changed from their defaults
# to exaggerate differences. With the default transition bandwidths,
# these are all very similar because the filters are almost the same.
# In practice, using the default is usually a wise choice.
raw_filter.filter(
l_freq=freq - bandwidth / 2,
h_freq=freq + bandwidth / 2,
# no negative values for large bandwidth and low freq
l_trans_bandwidth=min([4 * bandwidth, freq - bandwidth]),
h_trans_bandwidth=4 * bandwidth,
)
raw_filter.apply_hilbert()
epochs_hilb = Epochs(
raw_filter, events, tmin=0, tmax=n_times / sfreq, baseline=(0, 0.1)
)
data[:, :, idx] = epochs_hilb.get_data()
power = EpochsTFRArray(epochs.info, data, epochs.times, freqs, method="hilbert")
power.average().plot(
[0],
baseline=(0.0, 0.1),
mode="mean",
vlim=(0, 0.1),
axes=ax,
show=False,
colorbar=False,
)
n_cycles = "scaled by freqs" if not isinstance(n_cycles, int) else n_cycles
ax.set_title(
"Sim: Using narrow bandpass filter Hilbert,\n"
f"bandwidth = {bandwidth}, "
f"transition bandwidth = {4 * bandwidth}"
)
```

## Calculating a TFR without averaging over epochs#

It is also possible to calculate a TFR without averaging across trials.
We can do this by using `average=False`

. In this case, an instance of
`mne.time_frequency.EpochsTFR`

is returned.

```
n_cycles = freqs / 2.0
power = epochs.compute_tfr(
method="morlet", freqs=freqs, n_cycles=n_cycles, return_itc=False, average=False
)
print(type(power))
avgpower = power.average()
avgpower.plot(
[0],
baseline=(0.0, 0.1),
mode="mean",
vlim=(vmin, vmax),
title="Using Morlet wavelets and EpochsTFR",
show=False,
)
```

```

<class 'mne.time_frequency.tfr.EpochsTFR'>
Applying baseline correction (mode: mean)
```

## Operating on arrays#

MNE-Python also has functions that operate on `NumPy arrays`

instead of MNE-Python objects. These are `tfr_array_morlet()`

and `tfr_array_multitaper()`

. They expect inputs of the shape
`(n_epochs, n_channels, n_times)`

and return an array of shape
`(n_epochs, n_channels, n_freqs, n_times)`

(or optionally, can collapse the epochs
dimension if you want average power or inter-trial coherence; see `output`

param).

```
power = tfr_array_morlet(
epochs.get_data(),
sfreq=epochs.info["sfreq"],
freqs=freqs,
n_cycles=n_cycles,
output="avg_power",
zero_mean=False,
)
# Put it into a TFR container for easy plotting
tfr = AverageTFRArray(
info=epochs.info, data=power, times=epochs.times, freqs=freqs, nave=len(epochs)
)
tfr.plot(
baseline=(0.0, 0.1),
picks=[0],
mode="mean",
vlim=(vmin, vmax),
title="TFR calculated on a NumPy array",
)
```
