Dear all,
I have searched but I was not able to find the exact structure of the sig files generated by i.gensig.
Can anyone point me out what is the structure of the the SIGNATURE
EXAMPLE
#Value 1
643
114.958 107.323 128.793
415.38
460.891 533.341
600.392 714.442 1071.21

As this is only used internally, I think the only documentation is in
the source:
http://trac.osgeo.org/grass/browser/grass/trunk/include/imagery.h#L50

#
#Value 1

= number of points in class
114.958 107.323 128.793
= mean values per band of the class
415.38
460.891 533.341
600.392 714.442 1071.21
= (semi)-matrix of band-band covariance

Hi,
inspired by Moritz's comments, I have added an example to
the manual page of i.gensig, see new "NOTES" section:
http://grass.osgeo.org/grass64/manuals/i.gensig.html
(likewise for GRASS 6.5 and 7)
