Sensitivities and average scores of the different HMMs for evolutionarily distant retroviral LTRs at low specificity.

The thresholds were the same as in the RepeatMasker comparison in Table 3. (*) indicates that at least some LTRs in the LTR set are in the training set of the HMM model. (**) indicates that the set was used as a test set.本次所用阈值与表3中RepeatMasker比对分析的阈值一致。(*) 表示该LTR集合中至少存在部分长末端重复序列（Long Terminal Repeat，LTR）属于隐马尔可夫模型（Hidden Markov Model，HMM）的训练集。(**) 表示该集合被用作测试集。
