Basics: do you have enough free space on your hard drive? Do you have write access to the directory where you are trying to save the image?

Next: can you share the image in question?

thank you for your patience, I can not upload the image without getting patient allowed ，however I run the itksnap in win 10 instead and it works well. anyway, thank you again, it is very kind of you.
