In the impl of SoftClusters on writeOut it calculates the centroid and writes it and when read(in) it reads the centroid in to the center.
In ClusterDumper it reads into the ClusterBase and does value.getCenter(); It should work normally right Robin On Wed, Feb 17, 2010 at 6:02 PM, Pallavi Palleti < pallavi.pall...@corp.aol.com> wrote: > Yes.
