  1. Rows show the results with the specified λ value and columns correspond to different values of L. The variable change point model and normal prior is used with motif width and motif specification (uni- or bimodal) listed in Table 1. For each dataset L, the top 2L starting points were used according to the MEME starting point selection procedure. For the rap1 test set, a different set of random starting points was used for each L. Entries labeled with an asterisk correspond to a trial in which the correct motif was not found, but one or two sites were correctly predicted by chance, with a spurious motif.
