Yes. I think that the default behaviour is to use the minc library magic
to make everything scalar. There is a volume_io option that allows this to
be turned off (I don't have time to look it up right now). Be warned,
however, that volume_io uses pointers to pointers to pointers for its
arrays (it was faster that way at the time that David benchmarked it). The
down side of this is that a complex vector short volume will have as much
pointer as data, even on a 32-bit system (one pointer for every 4 bytes of
data).
