Effect of the Bayesian motif prior on local search accuracy. The plot shows the average accuracy of the motif models discovered by conjugate gradient alone as a function of A, the total pseudocounts applied when deriving the PSFM from W. The starting point for conjugate gradient is derived from the consensus sequence for the planted motif using a value of B = 0.25. All experiments use the Random Negative Problem and DNA sequences and the OOPS data model. Each data point is the arithmetic mean (± standard error) for 100 independent experiments. Panel a shows results using FM motifs and panel b shows results using PSFM motifs.
