This looks a lot like errors caused by irregular sampling , the easies 
way to check is to do
mincheader your_file.mnc |grep irregular
if you get something - the easies way to fix is just to replace it with 
regular sampling (for example if you happen to have irregular sampling 
in xspace):

minc_modify_header -sinsert 'xspace:spacing=regular__' your_file.mnc
