Hi,
we encountered a problem when normalising images yesterday, using SPM99.
It seems that the normalisation procedure fails when images contain
negative voxel values.
When trying to normalise an image scaled to fit the full range of int16
the normalisation failed. Rescaling the image to [0,32767] fixed the
problem.
Is this behavior expected?
