Code

Python script used in Ultrafest V above to calculate and plot neutral contours. The script expects 2 files at runtime: 1 containing the contour traces of the word to be plotted, and a second with the traces of the neutral position. This code can be run from a unix style terminal with the command

$ python neutralContour.py coli.txt neutral.txt

here are sample contour traces and neutral traces.

This code depends on matplotlib, version 0.99 or better, along with the mplot3d toolkit

This code is under development - I would appreciate any feedback. If you want to use this code, but need help, I am happy to help
