Phylogibbs is an algorithm for discovering regulatory sites in a collection of DNA sequences, including multiple alignments of orthologous sequences from related organisms.The algorithm uses a Gibbs sampling strategy, takes the phylogenetic relationships of the input sequences rigorously into account, and assigns realistic posterior probabilities to reported sites using a novel annealing+tracking strategy.
SwissRegulon is a database of genome-wide annotations of regulatory sites. It contains annotations for 17 prokaryotes and 3 eukaryotes. The database frontend offers an intuitive interface showing genomic information in a clear and comprehensible graphical form.
TagScan allows searching for exact or near-exact matches between oligonucleotide queries of up to 60 bases and sequence databases comprising entire genomes or mRNA reference sequences. The smallest query allowed is 10 nucleotides long.
