How to read character changes from TNT

[Farah Aidil Fitri]

Hi all, 

I am trying to look for the synapomorphic characters from to relate with the node from the tree I produced in TNT. However I couldn't find the correct way of interpreting the data that I have. What does the 1 -> 01 meant? I do not think it relates with the character states that I build to come to this analysis.

Would anyone be so generous as to explain how to interpret this data?

Example: 

Char. 21 (3 steps) 

     Root: 1 

     Node 35: 1 -> 01 

     A_V : 01 -> 0 

     Node 48: 01 -> 1 

     Node 50: 01 -> 0 

     Node 38: 01 -> 0 

     Node 46: 01 -> 1 

Thank you.

1 -> 01 means a transition from state 1 to state 0 or 1, because both alternatives are equally parsimonious.
