MView is a tool for converting the results of a sequence database search (BLAST, FASTA, etc.) into the form of a coloured multiple alignment of hits stacked against the query. Alternatively, an existing multiple alignment (MSF, PIR, CLUSTAL, etc.) can be processed. In either case, the output is simply HTML, so the result is platform independent and does not require a separate application or applet to be loaded.
This server calculates the variability in each column of a multiple sequence alignment using the Shannon entropy (H) function. H values range from 0 (only one residue in present at that position) to 4.3 (all 20 residues are equally represented in that position).
LalnView is a graphical program for visualizing local alignments between two sequences (protein or nucleic acids). Sequences are represented by colored rectangles to give an overall picture of the similarities between the two sequences. Blocks of similarity between the two sequences are colored according to the degree of identity between segments.

Java Dot Plot Alignments (JDotter) is a platform-independent Java interactive interface for the Linux version of Dotter, a widely used program for generating dotplots of large DNA or protein sequences. JDotter runs as a client-server application and can send new sequences to the Dotter program for alignment as well as rapidly access a repository of preprocessed dotplots.
Dotter is a Linux graphical dotplot program for detailed comparison of two sequences. Here, every residue in one sequence is compared to every residue in the other sequence. The first sequence runs along the x-axis and the second sequence along the y-axis. In regions where the two sequences are similar to each other, a row of high scores will run diagonally across the dot matrix.

Divide-and-Conquer Multiple Sequence Alignment (DCA) is a program for producing fast, high quality simultaneous multiple sequence alignments of amino acid, RNA, or DNA sequences. The program is based on the DCA algorithm, a heuristic approach to sum-of-pairs (SP) optimal alignment that has been developed at the FSPM over the years 1995-97.
The Lagan Tookit is a set of alignment programs for comparative genomics. The three main components are a pairwise aligner (LAGAN), a multiple aligner (M-LAGAN), and a glocal aligner (Shuffle-LAGAN). All three are based on the CHAOS local alignment tool and combine speed (regions up to several megabases can be aligned in minutes) with high accuracy.
