I am very sorry for taking up everyone’s time!

I’m using the ITK-SNAP 4.2 executable, but I can’t open the DOM image, but I can’t understand at all why that’s the case, because all my previous images opened,and finished outlining without any problems.

The most likely reason for this is inconsistency in your DICOM series.
