Hi there
<div><br>
</div>
<div>I have a script where I create a map (using mapcalc) and I want
to attribute a color (gray for instance) but it ranges from 0 to 5 so I
cannot attribute gray0-1 neither gray0-255. What can I do to attribute
a color table that stretches its color attibution to the image max and
minimum values?</div>

How about creating a color rules file with percentages (instead of
values), then, regardless of the actual raster values, the colors will
be "automatically" spread between the min and max color. i.e.<br>
0% 0 0 0<br>
100% 255 255 255<br>
This will create a spread of colors from black to white. Now in your
script just apply this rules file. If the raster contains 5 values,
they will get colored black, dark grey, mid grey, light grey, and white.<br>
