Routing of astrovirus sequence data from GenBank to PAML input data files. Main features of astrovirus genomes are given at the top. Numbers in parentheses indicate the length of an ORF in nucleotides. RFS points to the ribosomal frame shift signal between ORF1a and ORF1b. In GenBank, the number of complete ORF2 sequences surpasses those of ORF1a or ORF1b. At the ultimate right side, resources are boxed to indicate the actions undertaken and results obtained.
