// nucleic acid templates "AGTCaguc" for the sequence builder 20070201 TH

// 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 torPREV = torNEXT (symmetry).

// all hydrogen atoms have been left out from this file, and they will be
// added later based on valences and formal charges.
