[Ifeffit] Primitive unit cell from .cif file

[joshua jason kas]

Hi everyone,
I was wondering if there is a simple (free) utility for producing a
primitive cell (not conventional) from an asymmetric cell and space group.
Basically, I want to be able to easily go from a crystallographic
information file to a primitive unit cell. I know that there are ways to
do this within applications like material studio, but these are expensive.
Any help would be appreciated.
Thanks,
Josh Kas
