I have done some restriction mapping and constructed cladograms using 
Hennig86.  I am not sure what the following values indicate: 
i) consistency index - what for eg. does a ci value of 54 compared to 
45 mean ?
ii) retention index - same question as above
iii) tree length - what for eg. does a tree length of 307 compared to 
288 mean ?  How does one "decide" what the best tree is - based on 
tree length ?

Hope someone can help.
