The fourth and final term used to compile the scoring function is the 'cutoff'. This controls the maximum distance at which the interactions will be calculated, the possible values ranging from 4 Å to 15 Å. With all four options there are a total of 96 possible scoring functions (8*12). Example scoring functions are 'radial-mean-reduced-6' (RMR6) and 'normalized frequency-cumulative-complete-8' (FCC8).
