[VoxBo] precision for stats cub?

[Daniel Drucker]

How much precision is needed for a stats cub? Is float sufficient or
does it have to be double?

(context: I'm writing some code to allow for writing of cubs from
matlab, using spm_vol as a go-between, and it wants to know.)

Also, how much does voxbo care about the voxels being [0.97 0.97 1] in
size? I.e., if I don't specify that information, what does voxbo do?
What if I specify it as [1 1 1] - how badly will that screw things up?
