Yes Ted, thanks...
In Italy we don't have Thanksgiving... so I forgot that you were on
holidays in USA... Excuse me for the disturb!

I worked here and meanwhile I've started to use CLUTO output for a first
cluster label estimation.

Anyway, I'm waiting for your response, to try to complete our system with
sensclusters.
Thank you so much.
