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

[darshan pai]

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
