\begin{Description}\relax
This function uses a specific configuration of Target column of the affylmGUI target file.
To know more about target file see affylmGUI help.
Each row of the column named Target, in the affylmGUI target file, describes the array on the basis
of the experimental design.
Each element needed for the construction of the data frame is separated from the others by an underscore. 
All the other elements refer to experimental conditions or clinical parameters.
The absence of a parameter NEEDS to be described in the Target file by NA
Considering two different conditions to be evaluated each row is made of 5 elements:
\verb+Time_Replicate_Control_cond1_cond2+ all separated by an underscore.
Having an experiment made of 9 arrays with 4 different experimental parameters 
the affylmGUI target file will look like:
Name   FileName        Target
mC1    M1.CEL  \verb+0_1_pos_0_NA+
mC2    M4.CEL  \verb+0_1_pos_0_yes+
mC3    M7.CEL  \verb+0_1_neg_0_no+
mE1    M3.CEL  \verb+24_2_neg_1_NA+
mE2    M6.CEL  \verb+24_2_NA_1_yes+
mE3    M9.CEL  \verb+24_2_neg_1_yes+
mI1    M2.CEL  \verb+12_3_0_pos_yes+
mI2    M5.CEL  \verb+12_3_0_pos_no+
mI3    M8.CEL  \verb+12_3_0_pos_no+
