[Insight-users] WSTITK use too much memory

[Wen Jiang]

Luis,
Thanks. But my problem was actually different. Let me make it clearer.
I am new to ITK and just compiled ITK on a laptop running Mandrake 9. I 
followed the instructions in 
Insight/Applications/SegmentationEditor/README.txt:

2. To run this application:

 cd INSIGHT_SOURCE/Applications/SegmentationEditor/Scripts
 INSIGHT_BUILD/bin/WSTITK Main.tcl

I only saw the widget prompt for the VTK, SegmentationEditror path and 
then it seemed stuck without any GUI shown. I did not even had the 
chance to specify an input to the SegmentationEditor. Looking at top 
display, WSTITK is taking several hundred meg and keep growing and 
crashed until it reached about 1.4G. Apparently this is a problem not 
related to the watershed algorithm but the compiling/library.
Did I miss anything during compiling VTK/ITK to get this weird problem?
