Tandem repeats, which consist of two or
more contiguous copies of a particular pattern of nucleotides, are
a major group of repeats in genomes. Tandem repeats are believed to have arisen from tandem
duplications, in which a stretch of DNA (which may contain several
repeating patterns) is transformed into two adjacent copies. Reconstructing
duplication histories for tandem repeats may yield valuable
insights into their functions and the biological mechanisms of
their creation and extension.

|How to Use NJtandem
If UNIX executable is downloaded, it needs to be decompressed first.
To execute the program, simply type NJtandem.
The program generates an evolutionary tree and outputs a string representation of the tree, as well as duplication blocks of the tree.
