[MINC-users] miopen_volume not opening file

[EJ Nikelski]

Hi Thomas,

  Could you provide the output of the following:

(1) mincinfo -version
(2) uname -a
(3) file my_test_minc_volume.mnc
(4) mincinfo my_test_minc_volume.mnc

  Which version of Ubuntu are you using?

-jim

I even tried running the first mini-program included in the MINC2 tutorials (code included below) and miopen_volume did not work here either. I'm assuming the code from the tutorial is correct and that there is some underlying problem with HDF5 or MINC2. I just reinstalled the latest versions of MINC2 (version 2.1) and HDF5 (version 1.8.6) on my Ubuntu system. I also ran "make check" on both before installing and they passed all the tests, so both libraries seem to be happy with the system. I really can't figure out what's going on because the programs and code should both be okay. Any ideas?
