Nisoverlay

Overlays a thresholded functional image map onto a corresponding structural image. The functional image can contain both positive and negative values (displayed as white and black, respectively), or positive values exclusively.

Invocation

java  Nisoverlay 

Nisoverlay window

Unlike the earlier program nisover, Nisoverlay will automatically expand the functional image to the same dimensions as the structural image, if possible.
