A tandem repeat in DNA is two or more adjacent, approximate copies of a
pattern of nucleotides. Tandem Repeats Finder is a program to locate and
display tandem repeats in DNA sequences. In order to use the program,
the user submits a sequence in FASTA format. There is no need to
specify the pattern, the size of the pattern or any other parameter. The output consists of two files: a repeat table file and an
alignment file. The repeat table contains
information about each repeat, including its location, size, number of
copies and nucleotide content. Clicking on the location indices for one
of the table entries opens a second web browser that shows an alignment
of the copies against a consensus pattern. The program is very fast,
analyzing sequences on the order of .5Mb in just a few seconds.
Submitted sequences may be of arbitrary length. Repeats with pattern
size in the range from 1 to 2000 bases are detected. Sequence information
sent to the server is confidential and deleted after program execution.
