fsleyes.views.powerspectrumpanel

This module provides the PowerSpectrumPanel class, a ViewPanel which plots frequency/power spectra.

class fsleyes.views.powerspectrumpanel.PowerSpectrumPanel(parent, overlayList, displayCtx, frame)

Bases: fsleyes.views.plotpanel.OverlayPlotPanel

The PowerSpectrumPanel class is an OverlayPlotPanel which plots power spectra of overlay data. PowerSpectrumPanel uses PowerSpectrumSeries to plot the power spectra of overlay data.

A couple of control panels may be shown on a PowerSpectrumPanel via ViewPanel.togglePanel().

PlotListPanel	The PlotListPanel is a FSLeyes control panel for use with OverlayPlotPanel views.
PowerSpectrumControlPanel	The PowerSpectrumControlPanel class is a PlotControlPanel which allows the user to control a PowerSpectrumPanel.

Melodic images

The PowerSpectrumSeries class uses a fourier transform to calculate the power spectrum of a time course. However, MelodicImage overlays already have an associated power spectrum, meaning that there is no need to calculate one for them.. So for these overlays, a MelodicPowerSpectrumSeries instance is used.

plotMelodicICs = <MagicMock name='mock.Boolean()' id='139881574968736'>

If True, the power spectra of MelodicImage overlays are plotted using MelodicPowerSpectrumSeries instances. Otherwise, MelodicImage overlays are treated as regular Image overlays, and VoxelPowerSpectrumSeries are used for plotting.

plotFrequencies = <MagicMock name='mock.Boolean()' id='139881574968736'>

If True, the x axis is scaled so that it represents frequency.

static defaultLayout()

Returns a list of control panel types to be added for the default power spectrum panel layout.

static controlOrder()

Returns a list of control panel names, specifying the order in which they should appear in the FSLeyes ortho panel settings menu.

__init__(parent, overlayList, displayCtx, frame)

Create a PowerSpectrumPanel.

Parameters

• parent – The wx parent object.

• overlayList – The OverlayList.

• displayCtx – The DisplayContext.

• frame – The FSLeyesFrame.

destroy()

Must be called when this PowerSpectrumPanel is no longer needed. Removes some property listeners, and calls OverlayPlotPanel.destroy().

getActions()

Overrides ActionProvider.getActions(). Returns all of the actions that are defined on this PowerSpectrumPanel.

draw(*a)

Overrides PlotPanel.draw(). Draws some PowerSpectrumSeries using the PlotPanel.drawDataSeries() method.

createDataSeries(overlay)

Overrides OverlayPlotPanel.createDataSeries(). Creates a PowerSpectrumSeries instance for the given overlay.

__annotations__ = {}

__module__ = 'fsleyes.views.powerspectrumpanel'

prepareDataSeries(ps)

Overrides PlotPanel.prepareDataSeries(). Performs some pre-processing on the data of the given PowerSpectrumSeries instance.

__plotMelodicICsChanged(*a)

Called when the plotMelodicICs property changes. Re-creates the internally cached PowerSpectrmSeries instances for all MelodicImage overlays in the OverlayList.
