[BiO BB] finding repeat sequences

There is a nascent article on the topic here (mostly about nomenclature right now):


If anyone would like to contribute to it, please do.

There are a number of programs available for finding repetitive sequences.  Since you're looking for tandem repeats, that narrows it down some.  There are differences in scale as well: are you looking for short or long repeating units?

The methods for finding repeats vary, too.  Some use a library of known repeats (good for larger repeating units), while others take a de novo, "all possible combinations" approach.

And gaps are an important consideration.  Some programs don't consider them.

Anyway, the article above lists a few programs.  It's also possible to use regular expressions.
