raxmlGUI: A Comprehensive Guide to Phylogenetic AnalysisraxmlGUI is a graphical user interface for the widely-used software RAxML (Randomized Axelerated Maximum Likelihood), which is designed to infer phylogenetic trees. This tool allows researchers and biologists to perform complex analyses without requiring deep programming skills, making it accessible for a broader audience. In this article, we’ll explore what raxmlGUI is, how to install it, its features, and practical applications in phylogenetic analysis.

What is raxmlGUI?

raxmlGUI is an intuitive graphical interface that simplifies the use of RAxML, which is considered one of the most efficient tools for maximum likelihood inference of large phylogenetic trees. The RAxML software is known for its speed and robustness, making it suitable for analyzing extensive datasets. The GUI removes the need to use command-line commands, allowing users to focus more on the analysis rather than the intricacies of installation and command syntax.
