std::vector<int64_t> gmx::AtomInfoWithinMoleculeBlock::atomInfo

Atom info for each atom in the block.

The typical case is that all atoms are identical for each molecule of the block, and if so this vector has size equal to the number of atoms in the molecule.

An example of an atypical case is QM/MM, where multiple molecules might be present and different molecules have different atoms within any one QM group or region. Now there are multiple kinds of molecules with the same connectivity, so we simply write out the atom info for the entire molecule block. Then the size equals the product of the number of atoms in the molecule and the number of molecules.

The vector needs to be indexed accordingly.
