Overview of the structural mapping with spatial averaging approach as used in the Python BioStructMap package. For any given residue within a PDB structure, all residues within a specified radius of the given residues are identified. The location of these residues within a given reference sequence is then found, with the assumption that user-provided data will be aligned to this reference sequence. Using selected residues and the corresponding subset of user-provided data, a function is called, returning (usually) a numerical value. For example, this function may return the mean of the respective data. Note that the provided data and the mapping function may take a diverse number of forms. This includes functions which apply some statistical test over a multiple-sequence alignment of genetic sequences (e.g. Tajima’s D). In this case, the function would apply the statistical test over the subset of codons which code for the selected residues. The returned value is then assigned to the original residue in the PDB structure. This process is repeated for all residues within the PDB structure. Results can be viewed as a heatmap displayed over the PDB structure.
