In short, DNAPARS computes the number of steps (changes in character states) for each topology, the difference in the number of steps between the best and each alternative topology, and the associated (large sample) variance of the differences. DAMBE can translate nucleotide sequences from any organism into amino acid sequences because it implements all known genetic codes. For the maximum parsimony method, a rooted tree is required to represent alternative topologies.

Part of the codes for sequence alignment in DAMBE are taken from the program CLUSTAL by D. The user can also use “custom splicing” to extract sequence segments that are not specified in the GenBank sequences. In short, one calculates the log-likelihood for each topology, the difference in log-likelihood between the best tree and each of the alternative topologies, and the variance of the differences estimated by resampling methods such as bootstrapping.

DAMBE features a user-friendly Windows interface with extensive on-line help. A simple method for estimating evolutionary rates of base substitutions through comparative studies of nucleotide sequences. This includes nucleotide, amino acid and codon usage analysis, compositional analysis based on dinucleotide and diamino acid frequencies, quantification of the effect of GC and T A frequencies on exon and CDS lengths, and the methylation effect on codon usage bias.

    Data Analysis in Molecular Biology and Evolution Xia

    Nucleotide-based distances include the one-parameter ( synonymous and nonsynonymous distances. A substitution model is characterized by frequency parameters and rate ratio parameters, and it is important to know the empirical substitution patterns in order to decide which substitution model to use in analyzing sequences. DAMBE can translate nucleotide sequences from any organism into amino acid sequences because it implements all known genetic codes.

    In short, one calculates the log-likelihood for each topology, the difference in log-likelihood between the best tree and each of the alternative topologies, and the variance of the differences estimated by resampling methods such as bootstrapping. DAMBE solves this problem by aligning the protein-coding nucleotide sequences against aligned amino acid sequences. Sequences can be as long as 32,768 bp.

    DAMBE takes the same approach but uses the Newman–Keuls test that is better for multiple comparisons. DAMBE does the same computation but uses the Newman–Keuls test which is more appropriate for multiple comparisons. It is often necessary to evaluate the relative statistical support for alternative phylogenetic hypotheses such as alternative phylogenetic trees. The last is necessary for doing bootstrapping and jackknifing with codon-based methods such as synonymous and nonsynonymous distances.
