[MINC-development] MINC2 file with floating-point voxels and slice normalization

[Vladimir S. FONOV]

Hello Everybody,

I came across a following problem -  I have got a minc volume with float
 type, but with image_max and image_min specifying range for each slice.

It turns out that there is actually no normalization performed in the
actual voxel values (as one would expect) and MINC1 api while dealing with
this file forks properly.

Unfortunately, MINC2 api checks if the image_max and image_min variables
 have dimension more then 1 and if it is the case, the inter-slice
normalization is enabled  (i.e see
https://github.com/BIC-MNI/libminc/blob/master/libsrc2/volume.c#L1122 ).

So, the question to MINC founding fathers - should MINC2 api be modified to
make sure that no inter-slice normalization happens when voxel type is
float, or is there any some other considerations?
