Execution time (a) and memory consumption (b) of Structuprint, as a function of the atom count (n). The runtime complexity is O(n), whereas the memory complexity is \( \mathrm{O}\left(\sqrt{\mathrm{n}}\right) \). The uneven distribution of atom counts reflects the composition of the Protein Data Bank. As of March 2015, ~99 % of entries in the PDB had an atom count of 61,000 or less, with the overall mean being 9,006 atoms
