I used the Neighbor-joining algorithm on a distance matrix and obtained all the branch lengths - internal and external. I need to now draw the tree - in both line format ("rectangular" format) and Newick format. This seems silly, but I'm stuck with not knowing where or how to begin.

Note that I am not looking for any computer code at this point. I'm just stuck with not knowing how to start - for either format. Would appreciate any help.

Thanks,

Joe

Hi arnstrm, thanks for the response. Actually, I am very familiar with MEGA and use it on a regular basis. I am writing code for another application that requires that I make the trees myself using code, not a GUI. The part I am stuck at is not the code but the procedure for going from having computed all the branch lengths to actually depicting the tree in the form of a line diagram and in Newick format.

I am requesting help with that.

Thanks.
