4D Volume Visualization

A tool for visualizing vector-valued volumetric data, which has become more common recently in medical imaging (e.g., 3D + time, multi-modal acquisition). The function accepts a 4D matrix, allowing the user to interactively select the 4th dimensional component to display. The 3D volume for the particular component is shown in a neurological coordinate frame with three orthogonal planar views along with a built-in 'slice' visualization. The user may also supply a cell array of colormaps, which populate a menu within the gui.
