XYZCoordinates
XYZCoordinates
Section System::Coordinates
Type string
If PDBCoordinates is not present, the program reads the atomic coordinates from
the XYZ file specified by the variable XYZCoordinates – in case this variable
is present. The XYZ format is very simple: The first line of the file has an integer
indicating the number of atoms. The second can contain comments that are simply ignored by
Octopus. Then there follows one line per atom, containing the chemical species and
the Cartesian coordinates of the atom.
WARNING: By default the coordinates are treated in the units
specified by Units and/or UnitsInput, which
means Octopus might expect xyz files to be in atomic units. If
you want the XYZ file to be read in Angstrom, as most codes do,
you can set the variable UnitsXYZFiles to
angstrom.
