Pattern matching language and tools

Developed at IRISA, a French academic research institute, Logol is a pattern matching grammar language and a set of tools to search a pattern in a sequence (nucleic or proteic).

It includes a Linux command line tool and a graphical designer.

Software is free and open source, under CeCILL license

You can also use it on the GenOuest platform online (with restrictions) or via command-line with a GenOuest account.

Sample explanation

This grammar searches in a sequence the term "aaa", then the term "acgt" saved as variable R1, and at least the content of variable R1 ("acgt" again).
