Hi Joshua,
I assume you mean in the context of an MRC file's header?
I believe bhead, from the bsoft program suite, should do what you want.
http://lsbr.niams.nih.gov/bsoft/programs/bhead.html
Note that until relatively recently not all software packages agreed on
the definition of this origin, so if you notice strange behavior, take a
look at the MRC2014 paper:
Cheng, A. et al., 2015. MRC2014: Extensions to the MRC format header for
electron cryo-microscopy and tomography. Journal of Structural Biology,
192(2), pp.146–150.
Hope this helps
Alexis
