deduceElementSymbol
The problem here stems from the fact that developers have not fully understood the PDB specifications -- and that those have changed. The actual rules are as follows (using 1-based numbering: 1) Chemical symbols may be in columns 77 and 78 for total disambiguity. 2) Only valid chemical symbols should be in columns 13 and 14 These are the first two characters of a four-character field. 3) Four-character atom names for hydrogen necessarily start in column 13, so when that is the case, if the four-letter name starts with "H" then it is hydrogen regardless of what letter comes next. For example, "HG3 " is mercury (and should be in a HETATM record, not an ATOM record, anyway), but "HG33" is hydrogen, presumably. This leave open the ambiguity of a four-letter H name in a heteroatom set where the symbol is really H, not Hg or Ha, or Ho or Hf, etc.- Parameters:
isHetero
-- Returns:
- an atom symbol
