[GRASS-user] i.gensig- Error because I'm obtaining negative values in covariance diagonal

[António Rocha]

Greetings

I'm using i.gensig and I'm having some problmes while generating 
signature files. Why? bcause my covariance calculus is placing negative 
values in the diagonal which is impossible. Has anyone detected any 
problem with i.gensig?

Thanks
Antonio
