Kris,
The info for the mask data volume is:
This is a data volume.
Origin: 0 0 0
Spacing: 1 1 1
Size: 148 120 120
Space: Unknown
Volume: 2.1312e+006
Min/Max: 0 33195
I tried to ftp the session to you but the computer I work at won't allow
it, so I included the screen shot you asked for. Also, I adjusted the
window/level was to get it to show some of the different gray values.
Another thing to add about the scan I was working with: The CT scan was
originally a .img file but I needed to reorient it in ImageJ and then
saved it as a series of .tiff files( .img wasn't a save option). Seg3D is
only doing this to files that I first altered in ImageJ and saved as a
series of .tiff files.
Thanks again for your help.
