I have a set of sequences and a tree topology for these sequences.
Is there an available tool that can make random mutations to the sequences given a specific position on the tree?
assuming I have this tree : (A,(B,(C,D)1)2)3;
A,B,C and D are species inside the tree.
I want to lets say select internal node 3 and make one random mutation to all species within this node.
Then take node 2 and make one other random mutation to all species there... and so on for all internal nodes in the tree where the choice if a mutation exists or no on this edge is also chosen randomly.
Is there any available tools? Otherwise I would implement one on my own?
