results from the GB model in AMBER 7 and 8 should match, I've done that
test myself. Make sure that you look at the new variable RGBMAX, it wasn't
in AMBER7 and can affect the comparison. In AMBER7, the RGBMAX was
effectively infinite. Otherwise the results will be completely
comparable, at least
for IGB=1.
