Figure 4

ROC plots showing sensitivity and specificity of TE detection among 2145 FGENESH models (1824 TE and 303 presumed genes) based on the percent of coding sequence masked using two methods. In one method BAC sequences were masked using an absolute frequency threshold of 0.8. In the other, masking was performed using RepeatMasker with the MIPS REcat library. ROC plot comparison of the maximum area under the curve resulting from the two plots showed that they are not significantly different (see main text for details).
