[Mristudio-users] Loading an Image and Changing Pixel Dimensions

[susumu]

Yes, I think the reason is these "minus" numbers. Please replace these bad
numbers by activating the windows (choose "Raw Image" format), change them
to any positive numbers, and choose "Analyze".

This is an interesting bug,,,,,

I am still wondering why your width parameter says
-0.9375 . I never seen a negative slice thickness. 
Does this Analyze file open in MRIcro?
I think maybe u need to check ur Analyze header and
change it to 0.9375 and check what happens
