Thank you Deep. I would have to automatically create several thousands 
of controls. To draw the gene map, I load a file with gene positions (in 
the genome) and gene names (plus other things which are not concerned 
with my problem). Then I draw the (huge) map. Therefore, I should be 
able to know where in the picture each gene is drawn.

Cheers

Patrick
