On the Value of Intra-Motif Dependencies of Human Insulator Protein CTCF
Figure 6
This PCT is an example of a small tree from a position in the motif that shows little statistical dependencies. We observe that the first layer of the tree is completely fused, which means that information about the nucleotide of position 12 is neglected. The tree partitions the context sequences according to the second and third predecessor (position 11 and 10), whereas the fourth predecessor (position 9) is also neglected. This example shows that the PCTs are capable of neglecting one or more context positions completely if they do not contribute sufficient additional information.
