Area of Science:
- Molecular Biology
- Evolutionary Biology
- Bioinformatics
Background:
- The MODELTEST package provides a computational tool for selecting DNA evolution models.
- The source code and documentation are publicly available online.
Purpose of the Study:
- To introduce and describe the functionality of the MODELTEST program.
- To provide researchers with a method for selecting appropriate models of DNA evolution.
Main Methods:
- Utilizes log likelihood scores to evaluate different models of DNA evolution.
- Compares various evolutionary models against empirical data.
Main Results:
- Identifies the specific model of DNA evolution that best fits the provided dataset.
- Provides a quantitative measure (log likelihood) for model comparison.
Conclusions:
