3-D grids were updated in the May 2015 release to reflect the remapping to the new Allen Mouse Common Coordinate Framework (CCFv3), higher resolution computation and new compress data format. 3-D grids from the October 2014 release (mapped to CCFv2) can be access through our data download server (see instructions).
