Helical packing arrangement decoy discrimination using a data set of 71 sequences with 2 or more TM helices (n = 71) and a data set of 57 sequences with 3 or more helices (n = 57).

Accuracy reflects the frequency at which the native or native model helical packing arrangement achieved the highest score compared to the decoy set.该准确率指标表征了相较于诱饵集（decoy set），天然态结构或天然模型的螺旋堆积构象取得最高得分的发生频次。
