	%NNDataPoint_ST_REG is a data point for regression with structural data.
	% It is a subclass of <a href="matlab:help NNDataPoint">NNDataPoint</a>.
	%
	% A data point for regression with structural data (NNDataPoint_ST_REG) 
	%  contains the input and target for neural network analysis with a subject with structural data (SubjectST).
	% The input is the structural data of the subject.
	% The target is obtained from the variables of interest of the subject.
