Dear all, Thanks to all the members that answered my question: Does anybody know a free software for drawing high quality haplotype networks? Below I compile the main ideas: - To use Network software (http://www.fluxus-engineering.com/sharenet.htm) - To use TCS (http://darwin.uvigo.es) - To use SplitsTree (http://www.splitstree.org) - To use any graphics software such as Illustrator or Corel Draw - To use Network and import the wmf file to Illustrator to touch it up/improve the colour/resolution. Basic functions in Network are free, though for more spiffy/efficient things you need to buy it. - To use Export the TCS network as a postscript and improve with Illustrator, Inkscape, CorelDraw, etc. Dra.
