class fsleyes.plotting.timeseries.FEATTimeSeries(*args, **kwargs)[source]

Bases: fsleyes.plotting.timeseries.VoxelTimeSeries

A VoxelTimeSeries class for use with FEATImage instances, containing some extra FEAT specific options.

The FEATTimeSeries class acts as a container for several TimeSeries instances, each of which represent some part of a FEAT analysis. The data returned by a call to getData() on a FEATTimeSeries instance returns the fMRI time series data (filtered_func_data in the .feat directory).

The extraSeries() method may be used to retrieve a list of all the other TimeSeries instances which are associated with the FEATTimeSeries instance - all of these DataSeries instances, in addition to this FEATTimeSeries instasnce, should be plotted.

For example, if the plotData and plotFullModelFit settings are True, the extraSeries() method will return a list containing one TimeSeries instance, containing the full model fit, for the voxel in question.

FEATEVTimeSeries A TimeSeries class which represents the time course of an EV from a FEAT analysis.
