Hi again,

   I've found a much better work around - I must be tired not to have thought of that before....

Since the results window does give me values for the total area measured, the mean IntDen (mean of the means already calculated for each particle) and the number of particles I can:

mean IntDen (mean of the means already calculated for each particle) x number of particles = total IntDen

total IntDen/ total area = mean grey value (of the whole area measured irrespective of the number of particles).

This is much better than manually treating each image but if anyone knows a better way to do this, such as a way to get ImageJ to produce these values without carrying out the calculations in Excel after I'd greatly appreciate it.
