. . . . . . "Tree Gibbs Sampler: identifying conserved motifs without aligning orthologous sequences" . . . "Summary: Tree Gibbs Sampler is a software for identifying motifs by simultaneously using the motif overrepresentation property and the motif evolutionary conservation property. It identifies motifs without depending on pre-aligned orthologous sequences, which makes it useful for the extraction of regulatory elements in multiple genomes of both closely related and distant species. Availability: The Tree Gibbs Sampler software is freely downloadable at https://compbio.iupui.edu/xiaomanli/LiSoftware/retrieve.php?ID=tgs Contact:shawnli@iupui.edu" . . . . . . . .
