About SIMMAP Software

SIMMAP is a post tree analysis program for making inferences about molecular and morphological character evolution. SIMMAP is similar in purpose to MacClade. Inferences are based on sampling character histories from the posterior distribution of character histories on a phylogeny. SIMMAP does not rely on parsimony, but employs a new method for the stochastic mapping of characters (see Nielsen, 2002). SIMMAP was written for scientists interested in the analysis of character evolution and educators teaching about the principals of stochastic models of sequence evolution.

Program Features
  1. Stochastically map molecular or morphological characters (mutations) on a phylogeny.
  2. Estimate covariation between molecular or morphological characters.
  3. Estimate dN and dS, while accounting for model and tree uncertainty.
  4. Estimate a wide variety of descriptive statistics for patterns in molecular or morphological evolution.
  5. Use sampling from predictive distributions to approximate null distributions and assign significance (covariation, dN, dS).
  6. Manipulate data sets and trees.
  7. Many more... (see help documents for more information)
System Requirements

SIMMAP was written for Apple's Mac OS X operating system. It is compatible with OS versions 10.3.9+ (However, recent fixes and new features have not been tested on versions before 10.4). Unfortunately, SIMMAP will not run on OS 10.2 or earlier. For more information on SIMMAP development and system requirements, click here.
