SDRAP is a web application which annotates DNA segments in DNA rearrangement precursor and product genomes which describe the rearrangement, and computes properties of the rearrangements reflecting their complexity. The annotated segments sought by the software are analogous to MDSs, IESs, and pointers in ciliate DNA rearrangements.

Assembly Words

This application draws the assembly graph, chord diagram, and circle graph defined by the word.
