[Neuroimaging] Convert Atlas from 1mm to 2mm

[Samuel St-Jean]

While we are at it, you can also consider upsampling your data to 1 mm 
to fit on the atlas as well, especially if this atlas contains label for 
finer structure like deep gray matter which are only a few voxel wide. 
In all cases, be sure they are registered/the affine can make both 
datasets correspond either at 1 mm or 2 mm.
