No worries -- If there's any real "bug" here, it's in  
ImageSeriesReader which shouldn't be reading more than it has  
allocated space for.

That said, richer documentation than the one-liner specified for  
GE4ImageIO would have been helpful.

I agree.  It's a little disappointing that there's a processing  
dichotomy between "slice" and "volume" formats, but I normally assume  
that any data in a slice format will be converted to a volume format  
as a preprocessing step before any analysis.  Maybe people have a  
desire or need to keep things in slice formats and unifying things  
would be helpful.
