dowser
B Cell Receptor Phylogenetics Toolkit
Provides a set of functions for inferring, visualizing, and analyzing B cell phylogenetic trees. Provides methods to 1) reconstruct unmutated ancestral sequences, 2) build B cell phylogenetic trees using multiple methods, 3) visualize trees with metadata at the tips, 4) reconstruct intermediate sequences, 5) detect biased ancestor-descendant relationships among metadata types Workflow examples available at documentation site (see URL).

Dowser provides a set of tools for performing phylogenetic analysis on B cell receptor repertoires. It supports building and visualizing trees using multiple methods, and implements statistical tests for discrete trait analysis of B cell migration, differentiation, and isotype switching. Dowser has 6 primary functions: 1. Reconstruct clonal germline sequences. 2. Build B cell lineage trees using multiple methods, such as maximum parsimony, maximum likelihood, and IgPhyML. 3. Reconstruct intermediate sequences within lineage trees using different methods. 4. Create publication-quality lineage tree plots. 5. Analyze trees to detect ongoing B cell evolution over time. 6. Understand B cell migration and differentiation.
