45 Tomtom is a tool for comparing a DNA motif to a database of known motifs. For an in-depth explanation of the Tomtom software see here_. | |

49 **Recommended Settings** | |
50 | |
51 We recommend most users use the Tomtom defaults of q-value for score, the cutoff of 0.5 and the Pearson correlation coefficent for distance metric. | |
52 | |
53 ---- | |
54 | |
55 **Parameters** | |
56 | |
57 We offer users the options of choosing which distance metric can be used to find matching motifs. Specifically, we offer the Pearson correlation coefficient, the Euclidean distance and the Sandelin-Wasserman Function. | |
58 | |
59 * The Pearson correlation coefficient measures the similarity between columns of position weight matrices (PWMs). | |
60 | |
61 * The Euclidean distance can be thought of as the length of the straight line between two PWMs. | |
62 | |
63 * The Sandelin-Wasserman function sums the column-wise differences between PWMs. | |
64 | |
65 We also offer the choice of E-value and q-value to threshold the results returned by Tomtom. | |
66 | |
67 * The E-value controls the expected number of false positives and can be any number. | |
68 | |
69 * The q-value controls the false discovery rate and is a number between 0 and 1. | |

73 Note that at this time we only offer Tomtom output in txt format. | |
