TOPALi

TOPALi is a remarkable open-source Java application that offers a wide range of statistical and evolutionary analyses of multiple sequence alignments (MSAs) via web services. This software provides functionalities like model selection, Bayesian analysis (BA), and Maximum Likelihood (ML) phylogenetic tree estimation. With TOPALi, users can swiftly detect sites under positive selection and easily locate recombination breakpoints.

One of the most noteworthy features of TOPALi is its efficient phylogenetic tree estimation, which is possible due to its usage of Bayesian and Maximum Likelihood principles. This application also provides its users incredible flexibility and control over model selection for their analyses, ultimately making it simpler to obtain the most suitable tree models for their datasets.

Furthermore, TOPALi stands out for its capacity to detect sites or regions that evolved under positive selection, seeing how top alignments are subjected to affirmative selection in many instances. With this software, users can easily detect the positively selected sites, assign a posterior probability value to each site, and generate an output displaying these features.

TOPALi also makes usage of a Bayesian approach to identify recombination breakpoints within the aligned sequences. It is a particularly useful feature in comparing the evolutionary histories of aligned DNA or protein sequences from closely related organisms.

Overall, this software is user-friendly, complete with the latest statistics and phylogenetic tools of high quality, and it represents a great choice for researchers and users who are seeking to perform multiple sequence alignments and explore their evolutionary processes.
