ARB Project
The ARB Project is a free software package for the phylogenetic analysis of rRNA and other biological sequences including DNA and protein sequence. It provides tools for import and assembly of genetic sequences from diverse organisms via an automated aligner module. The method was published in 2004.
The package offers two main editors—Primary Structure Editor and Secondary Structure Editor—for developing a phylogenetic tree. Visualization features allow users to compare biological sequences and phylogeny data from various organisms.
