Orthogonal Viewer Description:

The orthogonal viewer displays three orthogonal slices of the selected component like axial, sagittal and coronal. You can interactively navigate around the brain by clicking on a voxel in any of the orthogonal slices or by entering real world coordinates (See Options menu in Figure 2). The controls plotted below the slices are explained below:

BOLD Time course
BOLD signal is plotted for the data-set shown in the popup control for the current voxel. When a voxel is interactively chosen, you have to select the entry in the popup box to update the BOLD time course plot.
ICA Time course
ICA time course is plotted at the maximum voxel (Red), minimum voxel (dotted red) and at the current voxel (green). Real world coordinates are reported in the plot title.
Popup Control
Popup control is used to show the original data-sets used for the analysis. Mean is also included in the popup control and when clicked plots mean time course and standard error of mean for the current voxel.
Plot Button
Plots the top five components for the selected voxel for the viewing set.
