With MRIcroGL you could create two renderings. Choose a template without a cerebellum if you do not want it...

import gl
gl.resetdefaults()
gl.backcolor(255, 255, 255)
#open background image
gl.loadimage('spm152')
#open overlay: show positive regions
gl.overlayload('spmMotor')
gl.minmax(1, 4, 4)
gl.opacity(1,50)
#open overlay: show negative regions
gl.overlayload('spmMotor')
gl.minmax(2, -4, -4)
gl.colorname (2,"3blue")
