Motivation: Profile Neighbor Joining (PNJ) as implemented in ProfDist is computationally efficient in reconstructing very large trees. Besides the huge amount of sequence data the structure is important in RNA alignment analysis and phylogenetic reconstruction.
Results: For this ProfDistS provides a phylogenetic framework that uses individual RNA secondary structures in reconstructing phylogenies based on sequence-structure alignments - using Profile Neighbor Joining (PNJ) with manual or iterative and automatic profile definition. Moreover, ProfDistS can deal also with protein sequences.
