This point is further illustrated by considering the additional hydrogen types used in AlkEthOH. The We plot the fraction of simulation time that each reference atom type (x axis) is matched by a SMARTS pattern with a partial score of 100%. We tested eight different temperatures (y axis) and ran 10 simulations of 10,000 iterations each. Darker colors imply a higher rate of matching 100% of that reference atom type; see color bars at right. If we never found the reference atom type, the corresponding cell would be white, but this does not occur here.
