[MINC-users] change origin

[Andrew Janke]

Hi Anna,

The simplest way to do this is to change the start value for each dimension.

For example if you wish to change the origin of the zspace co-ordinate
from 45 to 47 then you need to subtract 2 off the start as such:

   minc_modify_header -dinsert zspace:start=-93  myfile.mnc
