Crann (pronounced 'crown') is the Irish word for 'tree'.
The program Crann has been developed in order to provide fast heuristic methods of detecting adaptive evolution in protein-coding genes. It is important that the user understands the advantages and limitations of these methods. It is also important for the user to know that the software is designed to perform a number of different tasks, however the interpretation of the results is left entirely to the user.
