I haven't used the rcube routine myself but
a look at the code suggests that it only
works for reading multiple 2-D images into
a 3-D resulting data volume.
If you set $PDL::verbose = 1 you'll get some
diagnostic output from the rcube() call. Of
course, you can just use rcols() to read in
each data set from your files and place them
in a larger data array yourself. rcube() is
just some shorthand for that.
Cheers,
Chris
