Version 4 contains a number of enhancements over MEGA 3.1. They include
Maximum Composite Likelihood method (MCL):
- Estimation of evolutionary distances.
- Construction of phylogenetic trees from MCL distances.
- Inference of patterns of nucleotide substitution including estimation of transition/transversion rate ratios (kappa1, kappa2), and the transition/transversion rate bias (R).
Real-time Caption Expert Engine:
- Generates publication-quality captions from analysis results.
- Captions are generated dynamically based on the analysis options used, and manual adjustments made within result explorers.
- Captions for all result explorers available in MEGA.
- Captions can be saved to a file, copied to an external program (Word, Excel, etc), or printed directly from MEGA.
