¥Controlling the mappings from voxel value to brightness
and opacity:
²Probably want to
make white matter be fully white.
Drag
#3 Brightness handle up to top, over to white matter value
²Probably want to
reduce Opacity to 0 for all low intensity voxels.
Drag
#2 Opacity handle to bottom, over to histogram trough value
åThen press Draw to force a re-rendering
Values below ÒBotÓ
are equivalent to ÒBotÓ
Values above ÒTopÓ
are equivalent to ÒTopÓ

Crv Þ curve between handles
# Þ changes number of handles
Line Þ restore straight line map
ÔHandlesÕ that let you change the shape of the
mapping functions
Horizontal axes
correspond to voxel values between ÒBotÓ and ÒTopÓ
