- Up to version 1.1: based on suffix tree as described in our
original publication [1].
- Since version 2.0: based on suffix array, which can be thought of as a
space-efficient representation of a suffix tree. Also gained in speed.
- Version 2.2: switched from locally varying GC content in sliding window analysis to
constant CG content. In other words, the expected aggregate shustring length,
Ae (cf. [1]) is the same for all windows.
- Version 2.3 (May 20,2007): improved user interface.
