% the file. The Implementation Version Name (0002,0013 is a description
% of the modality (16 characters max). These values must be updated
% together.
% Class UIDs generated by the Image Processing Toolbox have the following
% structure:
%
% IPT_UID_ROOT.3.x.y
%
% Where 3 is the (new) constant value for class UIDs, x is the constant class,
% and y is the individual instance of the class.
