                  what is the difference between the sum and num options
                  in v.rast.stats?<br>
                  comparing the results of the two columns they appear
                  to be the same, but<br>
                  I'm sure I'm missing something.<br>
                  Thanks for any pointers<br>

    sum is the sum of values and "num" (n) is the number of cells,<br>
    if you have all cells = 1,  in this case  sum = num<br>
    if this is not the case (all cells = 1) maybe something is wrong ...<br>
