Hello Dear:

 
I Downloded the ITK Software and started to study its help, I impoted the knee slices but I saw in a part of 

 
the Tutrial that I should load the segmentation label, by these commands: File /Load Data/Label 

 
Description/ ,  But there is not any "Load Data" During File , and I only found the , "Label Description" , as a 

 
subdirectory of the "Open " and  "Save", But I tried both of them to load the "MRIcrop-seg.label"  File, But I 

 
couldn't load the "MRIcorp-seg.label" and after opening the "Snap Label Editor" I didn't see the new loaded 

 
files, what's the problem?

 
Dear, another question is: Why do we need to load another segmented file, like "MRIcrop-seg.label" ,I do 

 
not have any separated file for the knee Segmentation, I want to start the segmentation (Manually, or 

 
Automatically) from zero , by ITK Software, Do you Direct me, Please?

 
Best Regards.
