It is possible that there is a header issue in your images. Please check if the header in your images is correct. Based on the error message you mention it seems that the values are all 0 or negative.
To check the header.
Please 1) open the image in BrainSuite,
2) Goto Tools->Volume Info
If you still have the problem, if you can post that information here I can have a look.
