[MINC-development] MINC2 api - hidden treasures

[Vladimir S. FONOV]

Hello Everybody,

I've been trying to make MINC2 API, NETCDF independent recently. And I 
have to say that it's been very frustrating experience so far.

Occasionally I come across pieces of code like this:
https://github.com/BIC-MNI/libminc/blob/master/libsrc2/volume.c#L98 
(written in 2004):

     if (volume->has_slice_scaling) {
       /* TODO: Find the slowest-varying spatial dimension; that forms
       * the basis for the image-min and image-max variables.  Right
       * now this is an oversimplification!
       */
       ndims = volume->number_of_dims - 2;
       dataspace_id = H5Screate_simple(ndims, hdf_size, NULL);
     } else {
       ndims = 0;
       dataspace_id = H5Screate(H5S_SCALAR);
     }

Which means that MINC2 files created with MINC2 API are always assumed 
to have more then 2 dimensions if slice normalization is enabled. And 
only provide 2D slice normalization.
