Step 8 GUI for removing artifactual components in second round of ICA. Topographical display of the ICA components derived in the second round of ICA in order of variance (largest to smallest). Selecting the gray button above a component will display the temporal, spectral, and spatial characteristics of the corresponding component. Within this “child” GUI, selecting the data button will display the time domain characteristics of the ICA component over each trial. The user can identify the type of artifact using the drop-down menu. This marks the component for deletion. Viewing a component will highlight the component name in green, and marking it for deletion will highlight it in red. Update button on the top left of the main GUI displays the averaged butterfly plot of the EEG data assuming the deletion of the marked components. Comp Mat button on the top left of the main GUI is used to visualize the components marked for deletion for quality control (x-axis is the component type and y-axis is the component number).
