[MINC-development] weird minc 2 bug

[Jonathan HARLAP]

Here's a neat one:

Take a CDF file, run it through mincconvert -2 to get the corresponding 
HDF file.  Now open both file in register (or just use 
mincinfo/mincheader).  You'll see that the dimension order is, as it 
should be, identical.

Now, the fun part.  Run mincinfo -dimnames on the two files, and observe 
the different dimension order.

This fun bug is great in that it's a subtle little glitch in mincinfo, 
but affects many little programs, such as mni-perllib's 
MNI::MincUtilities::get_dimension_order()

Example output below.

Cheers,
J
