That's not a quantity. You need to be able to say something like "I want 
to show with an error bar twice the standard error of the average 
distance between the terminal alpha-carbon atoms over my five 
simulations". Once you can do that you can start to construct commands 
with g_dist and g_analyze to achieve it.
