The function ec_plotCortex plots native or template cortical reconstructions from any hemisphere and angle. Electrodes and ICs can be overlaid with the d input: a table containing coordinates/vertices and other data for each electrode. Missing fields in d are filled with default values. The size, color & border of each electrode can be modified in d. For example, color could reflect activation magnitude or IC weights.
The function ec_summaryCh_specPlot plots summary statistics and single-trial timecourses across individual channels or ICs using output from ec_summaryCh_spec. The location of each electrode is displayed on each subject's native cortex. For ICs, the entire electrode montage is plotted on each subject's native cortical surface, colored by z-scored IC weights. The electrode with highest covariance for a given IC is highlighted with a green border.
The function ec_plotTimesCortex plots cortical activity maps across time. This can plot metrics like t-values, classification scores, and connectivity strengths. Can plot thousands of channels/sources at once. Supports plotting multiple spectral frequencies.
