114 Calculate TADs | |
115 ============== | |
114 | 116 |
115 **What it does** | 117 Topological associated domains (TADs) are regions on the DNA which tend to interact within the region a lot, but not outside their boundaries. More information_. |
116 | 118 |
117 Uses the graph clustering measure "conductance" to find minimum cuts that correspond to boundaries. | 119 Calculation |
120 ------------ | |
121 ``hicFindTADs`` computes the TAD regions in two steps: In a first step it computes a TAD-separation score based on a z-score matrix for all bins. The z-score is defined as: | |
118 | 122 |
123 “The absolute value of z represents the distance between the raw score and the population mean in | |
124 units of the standard deviation. z is negative when the raw score is below the mean, positive when above.” | |

131 | |
132 In our case the distribution describes the counts per bin of a genomic distance. In a second step the local minima of the TAD-separation score is evaluated with respect to the surrounding bins to assign a p-value. Two multiple testing corrections can be applied to filter the results: `Bonferroni <https://en.wikipedia.org/wiki/Bonferroni_correction>`_ or the `false discovery rate <https://en.wikipedia.org/wiki/False_discovery_rate>`_. | |

135 Input | |
136 ----- | |
137 | |
138 Parameters | |
139 __________ | |
140 - contact matrix to compute the TADs on | |
141 - minimum window length | |
142 - maximum window length | |
143 - step size | |
144 - multiple testing correction | |
145 - minimum threshold | |
146 - minimum distance | |
147 | |
148 | |
149 hicFindTADs tries to identify sensible parameters but those can be change to identify more stringent set of boundaries. | |

151 Output | |
152 ------ | |
153 | |
154 - Boundary positions as a bed file | |
155 - Matrix with multi-scale TAD scores as a bedgraph | |
