The diversity of the influenza A virus proteome was studied by creating subsets of the influenza A protein sequence alignments, comprising (1) avian sequences, subdivided into 3 decades (1977 1986, 1987–1996, and 1997 2006); (2) H5N1 viruses, subdivided into avian and human isolates; (3) circulating human subtypes, namely H1N1, H3N2, and H1N2.
The SDR sequence (subdivided into two wedges) has a maximum width of 85 km and is not continuous parallel to the margin, but is interrupted at the central portion of the Uruguayan margin.
All FRT-like sequences were subdivided into classes and subclasses based on their sequence features.
Generally, sequences are subdivided into system tracts based on objective criteria including types of bounding surfaces, parasequence-set distributions and the position within sequences (Wagoner 1995; Posamentier et al. 2009).
In addition, the 2DL5 sequences were subdivided according to their linkage, either to 2DS3 or 2DS5, as well as their presence in either the centromeric or telomeric part of the locus (Figure 3B).
Up till SCOP release 1.75, protein sequences are subdivided into a hierarchical order of class (cl), fold (cf), superfamily (sf), family (fa) and domain dm).
The sequences are subdivided into libraries, which are labeled with a three-letter code, with the corresponding restriction enzyme listed between brackets.
In all the resulting topologies, ingroup sequences were subdivided into the same two groups as in the complete analysis: sFRP-3/4, frizzled-5/8, frizzled-1/2/7-3/6 and sFRP-1/2/5, frizzled-4, and frizzled-9/10.
Briefly, larger sequences were subdivided into 10 kb fragments, and trained for 100 epochs using the k-batch training method, along with any leftover fragments exceeding 3 kb in length.
To potentially increase the recovery rate, the remaining 887 T-box sequences were subdivided on basis of the taxonomy of the species and taxonomic class-specific HMMs were built as before.
The sequences were subdivided into groups based on the source's genotype: All-Williams (AW) derived from the closely related and highly inbred cultivars Williams and Williams82 [ 44, 45] and Non-Williams (NW) derived from all other G. max cultivars.
