  • GIMSAN - web application/server for motif-discovery equipped with a practical and reliable statistical significance analysis. It is also available as a stand-alone application on Unix.
  • ALICO - Alignment Constrained null set generator: a framework to generate randomized versions of an input multiple sequence alignment that preserve some of its crucial features including its dependence structure.
  • GibbsILR - motif-finder that optimizes for the incomplete likelihood ratio (ILR)
