Hi Bruce,

Thank you for your reply.

I am sending now a file called 013.tar.gz via ftp. And this is not the worst...there are other with more regions that have not been considered in the segmentation process. I would like to know how could I cope with GM editions, as I am doing with control points with WM.

Yours sincerely,

Rosalia
