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.

Hi Elizabeth,
One other thing I forgot to ask for, can you also send the info for
the masked data volume? As far as I can tell from what you've sent so
far everything looks like it should be working. My current guess is
that there are a very few discrete values in the masked data so that
Seg3D applies a color map coloring these few discrete values the same
and having the data appear to be binary. Would you mind saving your
Seg3D session and ftp'ing to ftp.sci.utah.edu ? From there, please put
the session file in upload/ForKris . If this is not possible, please
select your masked data volume, open Tools->Window/Level Tool, and take
a screenshot of the full Seg3D window. I'm hoping the histogram
displayed by Window/Level Tool may give us some clues. You may also try
adjusting the window/level yourself to see whether the masked data
really is binary or is just being displayed that way.
Thanks!

Hi Kris,
Thanks for your response. I use the exact same process that you use for
Mask Data Filter so I don't have any different or additional steps to
add.
The info for my label volume says:
This is a label volume.
Origin: 0 0 0
Spacing: 1 1 1
Size: 148 120 120
Space: Unknown
Volume: 2.1312e+006
Label Count: 45284
Label Volume: 45284
Label Volume Percentage: 2.12481
The info for my data volume says:

I have also included some screen shots. Let me know if you need anymore
information and thanks again for the help.

Hello,
I will need some more information to help troubleshoot this
issue.
Would you please click on the "i" button on the right-hand Volumes
panel
for both the label volume and data volume you are using and email the
contents of the Volume Information that is displayed? I am
specifically
interested in the type of volume (it should say either "This is a data
volume." or "This is a label volume.") and the Min/Max values.
Here is the process I use for Mask Data Filter:
1. Create segmentation of data (will be stored in a label volume)
2. Open Mask Data Filter
3. Select the label volume containing the segmented data
4. Either click the Set Mask Label button from the Mask Data panel OR
go
to the Edit menu -> Set Mask Label
5. Select the data volume containing the data to be masked
At this point, you should have the label volume highlighted in a
salmon/pinkish color and the data volume highlighted in a purple color.
6. Click the Start button on the Mask Data panel
Does this match what you are doing? If not, please also email the
exact
steps you perform related to using the Mask Data Filter.
It also may be helpful if you can email four screenshots: one showing
the segmented data, one showing the data that you want to mask, one
showing the entire Seg3D window just before you click the Start button
on the Mask Data panel, and one showing the result of the mask data.

Hello,
I am having a problem with the Mask Data Filter. I am currently using
Seg3D
version 1.13.0 and am still new to the program. My task is to segment
pig
hearts from CT scans and create a gray scale mask of the pig heart. I
have been
using the Mask Data filter to create my final mask of the heart but
the
weirdest thing keeps happening. The tutorial I have says that Mask
Data
is
supposed to create a gray scale mask but it will alternate between
giving me a
gray scale mask and a binary mask. I don't know what cause it to
switch
back
and forth. Right now all it's producing is binary masks when I use it.
Does anyone know how to get Mask Data to only create a gray scale mask
(and no
binary masks) ?
