Non-overlapping of content and signal sensors. Fixed-length features such as start codons and donor sites are detected by signal sensors, which are used to score an entire context window surrounding the signal. To avoid double-counting, content sensors score only the nucleotides strictly between two signal sensors. In this example, the CTA at the end of the start codon sensor window and the CGA at the beginning of the donor site sensor window are not scored by the exon content sensor, even though they are part of the putative exon, since those bases are already scored by the signal sensors.
