Thanks. Some comments:

- The peak handling routines seems pretty specialized for a specific use
  case, and do not probably work with other kinds of data, which explains
  why they are not in Scipy.

- numpy.trapz = trapezoid method

Check the permissions for "simplex.py", it currently says "403 Access 
denied"

scipy.optimize.fmin implements the Nelder-Mead algorithm.
