interesting how come they got different scaling parameters... I assume
if prior conversion/preprocessing was somewhat uniform they all should
have had either set them to some values (like the 1st one) or just to 0
(like the rest).  probably all others were simply resliced into the
first one ;)

and each image corresponds just to a single volume, thus not to a
"chunk" thus previously you had 0th sample as an outlier -- its values
were not scaled properly upon providing its NiftiImage into
NiftiDataset.  now things should be better (I hope ;) )
