t-testing in IDL [message #58240]

I have two sample data sets with 20 years of 12 months simulations in
a lon/lat grid of 128 x 64. , i.e. 2x(20,12,128,64). I would like to
find the difference between the two simulations and find out which
differences that are significant at a 95% level. I have calculated the
annual average of my 20-year simulation, and also the standard-
deviation, but how do I perfom the t-test? I have looked at the
tm_test but haven't figured out how to apply it on my 4-D approach..
Thanks
