Other motif discovery tools improve performance by using discriminative algorithms, which take into account negative sets in the analysis. Motif discovery and transcription factor binding sites before and after the next-generation sequencing era. Abstract. Dispom yields an increased prediction accuracy compared to existing tools for de-novo motif discovery, suggesting that the combination of searching for differentially abundant motifs, inferring their positional distributions, and adjusting the motif lengths is beneficial for de-novo motif discovery. The tool parses the output of each motif discovery tool and maps the results to an object of class Motif, which is then compared to the known motif represented by the Rfam seed alignment.
