I'm using Mac OSX Mavericks and have downloaded LaTex. I am currently learning how to draw phylogenetic tree. Can someone teach me?

I have copied a sample of code for the phylogenetic tree. it uses the newicktree package. But my compiler outputs file"...sty" not found.

    Welcome to TeX.SX! Please help us to help you and add a minimal working example (MWE) that illustrates your problem. It will be much easier for us to reproduce your situation and find out what the issue is when we see compilable code, starting with \documentclass{...} and ending with \end{document}. That said, make sure you've either installed the package correctly or that the package (the sty file) is in the same directory as your tex file. – Sean Allred Oct 4 '14 at 13:22
  • Thanks @SeanAllred. I have installed the basic-mactex only. Can you tell me what packages do I still have to install? plus, I never have minded whether my tex file are in the same directory. – programmer Oct 4 '14 at 13:26

    It looks like it's only available here: cbr.jic.ac.uk/dicks/software/newicktree. Download the sty file to the same directory as your tex file :) If it still doesn't work after that, open Terminal and run sudo tlmgr install pst-node pst-tree—a quick look at the sty file reveals that these are dependencies and I'm not sure which packages come in the 'Basic' MacTeX distribution. (It's always simpler to install the full distribution… trust me.) – Sean Allred Oct 4 '14 at 13:28
  • Great, i think I'm progressing. current problem : file "pst-tree.sty" not found. – programmer Oct 4 '14 at 13:31

    Leave it to install overnight. Things will be much simpler with the full installation. Otherwise, you are likely to keep discovering more and more things you need which is likely to get extremely annoying. (Especially if your connection is slow and you need to meet a deadline.) However, this may depend on what most easily annoys you so ymmv ;). – cfr Oct 4 '14 at 13:55
