Re-estimate the leaf values and HMM transition parameters based on the alignments from four and most recent DTAMs. 6.
A triphone system was then constructed based on the alignments derived from the monophone system, and a linear discriminant analysis (LDA) transform was employed to select the most discriminative dimensions from a large context (five frames to the left and right, respectively).
Based on the alignments, a distance matrix was constructed using DNAdist from the PHYLIP 3.6 package [15] with the default parameters in the Jukes-Cantor model option [16].
Gene structures were defined based on the alignments obtained, the conserved positions of introns in homologous bZIP genes, and the presence of canonical splicing sites (GT-AG).
Based on the alignments of the concatenated MLST gene fragments comprising 3284 sites with 383 parsimony informative sites SplitsTree4 [55] was used to construct a neighbor-net [56].
For example, to assess the accuracy of the trees based on the alignments, we compared the taxonomic assignments for each sequence with the structure of the phylogenetic tree.
Based on the alignments, phylogenetic trees were constructed using the neighbor-joining method with 1000 bootstrap replicates using the MEGA 3.1 program.
Based on the alignments maximum likelihood trees were constructed using a slightly modified (removing limitation for memory usage - see Methods S6 for the patch file) version of phyml [28].
Phylogenetic tree was constructed based on the alignments of PBoV1, PBoV2 and other viruses in the Parvoviridae family, the results indicated that PBoV was grouped with other bocaviruses (HBoV, MVC and BPV) but formed a distinct cluster (Figure 2).
