Figure 1.

System diagram of CTF. This figure showed the system diagram of CTF. Different features (PWM, chromatin signatures, and any other features such as the distance to a TSS) were integrated into CTF. Combining these features, CTF called CRF framework to obtain the probability-like scores of TFBSs across the whole genome. The CRF model of CTF contained two states: transcription factor binding site (TFBS) state and non-TFBS (background) state.
