(For an illustration of a "span", see additional file 1: StralSV-RdRp_Suppl_Figure 1.docx.) All residue-residue pairs that are contained within a span's alignment are used to calculate the sequence variability data at the corresponding position in the query structure. The qualified hits (structure fragments from PDB with detected local similarities to the query structure) for six selected sequence positions (positional hits) of polio RdRp (positions identified in Figure 3 ) were categorized and quantified based on SCOP (Structure Classification of Proteins database; version 1.75, June 2009 release) identifiers [32] . ./cache/cord-319906-s7kzp795.txt ./txt/cord-319906-s7kzp795.txt
