17. Press #5 to initiate the clustering program--it will ask if
the settings are correct. The settings are the number of
clusters or sample locations, and the number of PC’s to
use for clustering. By default there will be 3 PC’s used and
15 locations to sample. If more sample locations are
desired, then this can be changed at this time. Up to 10
PC’s can be chosen, however 95% of the data is contained
within the first 3 PC’s. If these settings are acceptable,
then select YES or, to update the settings press NO. If NO
was selected, update the settings and press continue to
begin clustering the data. Once the data have been
clustered, the program status will say done and the
complete light will be lit. Press close window or F12 to
