<P>Hello Dear:</P>
<P><BR> </P>
<P>I Downloded the ITK Software and started to study its help, I impoted the knee slices but I saw in a part of </P>
<P><BR> </P>
<P>the Tutrial that I should load the segmentation label, by these commands: File /Load Data/Label </P>
<P><BR> </P>
<P>Description/ , But there is not any "Load Data" During File , and I only found the , "Label Description" , as a </P>
<P><BR> </P>
<P>subdirectory of the "Open " and "Save", But I tried both of them to load the "MRIcrop-seg.label" File, But I </P>
<P><BR> </P>
<P>couldn't load the "MRIcorp-seg.label" and after opening the "Snap Label Editor" I didn't see the new loaded </P>
<P><BR> </P>
<P>files, what's the problem?</P>
<P><BR> </P>
<P>Dear, another question is: Why do we need to load another segmented file, like "MRIcrop-seg.label" ,I do </P>
<P><BR> </P>
<P>not have any separated file for the knee Segmentation, I want to start the segmentation (Manually, or </P>
<P><BR> </P>
<P>Automatically) from zero , by ITK Software, Do you Direct me, Please?</P>
<P><BR> </P>
<P>Best Regards.</P>
