Moreover I want to base my PhD on string comparison algorithms and
similarity searches. So, someday, I have to write a tool or a plugin
that looks for a repeats and visualize them. If  only simple repeats
in genome is what you need I can write such kind a tool in a nearest
week. (use my email instead of a board)
