// currently there are hard-coded fixes for these issues:
// ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
// * atoms 0x10 and 0x11 use incorrect torsion indices (see the index checks);
// however this does not cause problems when psiPREV = psiNEXT (alpha-helix).
//
// * amino -NH3 group (is made???) by default (using formal_charge).
//
// * identification of met groups in LEU and VAL residues.
//
// * the 2nd ring in TRP residues can be identified in two different ways:
//
// this is the "correct way" (shown below):
//
// 23 29 - 28 - 27

// most of the hydrogens have been left out from this file, and they will be
