Manuel, you might be able to use grpstats to compute the means (centroid) of
each cluster on the original data. Then you could use pdist2 and min as in
my earlier post to locate the nearest centroid for each new point.
This would be reasonable for your trees based on ward linkage. If you had
been using other linkage values, this probably would not be the most
appropriate approach.
