Hi Gabriel,

Thanks for your reply.  For my application, the images vary with a  
function of time (slice number) and it is the average intensity  
(grayscale) of a number of slices that I require.  I will use the  
average projection type and see how I get on with that.  However,  
having found out that there is a scale applied to the sum slices  
process it would be good to find out what actually happens when the  
average projection type is used; i.e., is it a simply pixel by pixel  
average or not?


Regards,
Martin.
