In this panel, you can see some basic information about the adjusted ChIP-seq experiments: name; antibody; cell line and element number (The number of peak regions obtained in a ChIP-seq experiment, which overlap with a particular consensus motif binding site set). The background colours indicate the histogram colours of the experiments on the plot.
The histograms shows the summit distance distributions of the selected ChIP-seq data (a maximum of 3) related to a motif center. The PairShiftView allows users to examine the distribution of individual summi- consensus motif distances for three experiments. To smooth the graph, a 5 bp rolling bin is used in the histogram. Each curve represents one ChIP-seq experiment. The X axis represents the distance (measured in base pairs) from the middle of the given motif, which is marked as the “0” point. The numbering of the axis is consistent with the position weight matrix below the diagram. The Y axis shows the frequency of summit occurrences at the relative position (at a given base pair) relative to the motif center. In the case of well-defined protein topology with high overlap frequency and close DNA localization, the curve has a bell-like pattern (normal distribution-like).
These setting can filter the displayed data. You can set the minimum and maximum element number. After updating the page with “Refresh Page” button, the experiments with out of range values will be vanished from plot.

PairShiftView

In this mode, the frequencies of the different distance values between the motif and peak summit pairs for a given consensus binding site set are displayed in a histogram. To smooth the graph a 5 bp rolling bin was used. No more than three different experiments can be compared. The height of the curves shows the most frequent distance. In the PairShiftView mode, the data range and the consensus motif binding site can be set. An experiment can be also selected and displayed in the ExperimentView.
