avw_view(avw)
avw - a struct, created by avw_img_read
The navigation is by sliders and mouse clicks on the
images in any of the ortho views.
Fiducial points can be selected, which are returned
into mriFID or p.mriFID in the base workspace. These
points are given in meters, with an origin translated
from the center of the MRI volume to (0,0,0). +X is
right, +Y is anterior, +Z is superior, the default RAS
orientation of Analyze MRI files.
