Hi developpers, hi Paul,

First, let me congratulate you for your work. The new ITKSnap version
is great!!!
At this moment, I use the installed version, and I can now use it on
my dual screen computer. No crash any more.
I tested the brand new polygonal segmentation method. Its continuous
point drawing is much more comfortable than the previous polygonal
drawing.
The mesh export will help us a lot! It's great.

Unfortunately, I experienced a problem when I tried to save
segmentation data. I wanted to export it in Analyze format as usual...
but I had a black Image, with no information inside...

The steps:
Manual segmentation using the polygonal segmentation. ->Great!
Export stl volume from segmentation data. ->Great!
Export Analyze volume from segmentation. ->Black image.
I changed the label value from "1" to "20", and I had the correct
image with "10" as segmentation value for voxels.
A new test with "2" as label value gave me an image with "1" as
segmentation value.

It seems that after mesh export, label value is divided by 2.
Problem with casting value?
Not a major bug, but to be mentionned anyway.

Laurent.

I would like to point something. The problem occured when I open the
Analyze volume with MRicro, my usual viewer. If I re-open it as
segmentation data in Snap, label value is correct...

Laurent.
