  1. a TP (true positive) = conformer pairs with ST≥0.8 that passed the quadrupole filter.
  2. b FP (false positive) = conformer pairs with ST<0.8 that passed the quadrupole filter.
  3. c FN (false negative) = conformer pairs with ST≥0.8 that were filtered out by the quadrupole filter.
  4. d TN (true negative) = conformer pairs with ST < 0.8 that were filtered out by quadrupole filter.
