The brain scan is slightly rotated prior to reslicing, consequentially changing x, y, and z ranges of the image. When running the function with default settings, this may cause the reslicing not to work properly in some cases (range dependent): for example see attachment.

Created attachment 310 top of the head missing

Created attachment 311 correctly resliced

The order of actions by ft_volumereslice is now; 1) use the ranges (if specified) 2) otherwise use the dim (if specified) 3) otherwise use default bounding box (25 mm^3)

True, this is a hacked version of an mri scan that originally 256 by 256 by 256. I've tried to see how ft_volumereslice would deal with it if i had changed its dim to 256 by 256 by 176.
