Output Cluster IDs

Hi,

Was wondering if there was an easy way to modify the output file for the clustering script to modify the input file and show the centroid lat/lons that are assigned to the original lat/lons and possibly assign IDs to those centroid lat/longs (i.e. - Original Lat | Original Lon | Centroid Lat | Centroid Lon | Cluster ID (1,2,3,etc.))

Thank you,
