Extract Microstate Sequence as Character Labels

Converts integer microstate labels to character labels ("A", "B", "C", ...).

Usage

eegMicrostateSequence(x)

Arguments

x

A PhysioExperiment object with microstate labels in metadata(x)$microstates$labels.

Value

Character vector of length n_time with labels "A", "B", "C", etc. Each element corresponds to the microstate class assigned to that time point.
