Base-By-Base

Base-By-Base is a whole genome pairwise and multiple alignment editor. The program highlights differences between pairs of alignments and allows the user to easily navigate large alignments of similar sequences. Although Base-By-Base was intended as an editor and viewer for alignments of highly similar sequences, it is also provides many of the functions of other generic alignment editors.

In addition to visualizing genomes and protein sequences, Base-By-Base allows the user to estimate simple phylogenetic trees, calculate the numbers of conserved and non-conserved sequence positions, and test simple quantitative hypothesis using novel modifications.

Troubleshooting

If your system does not launch Viral Orthologous Clusters, it is probably missing Java Runtime Environment 1.5. Please see Java Web Start Setup and Java Web Start Tips for help.
