Ok as far as I can see it's
Category ID (class)
Mean vector (each value is the average for the category in each band)
Var(b1;b1)
Cov(b1,b2) Var(b2;b2)
Cov(b1,b3) Cov(b2,b3) Var(v3,v3)
it's this?
It would take me to perform a test with numbers and see what is what exactly.
Hi everyone
I have runned i.gensig and I would like to know where can I find some
information regarding the strucutre of the file? Just to know which value
refers to what
Thanks

From the g.manual i.gensig:
...the resultant signature file (containing the means and covariance
matrices) for each

the mean's and variance/covariance matrices is enough.
Didn't have a look yet but the Mean's ... matrices is I guess wrong. The
signature file probably
