PDB Utility Servers - Specification of PDB Coordinate Transformations
Some PDB Utilities require specification of a Transformation to Apply in the form of a text listing one or rotations and translations, in the order to apply them. Use Keywords rx ry rz for rotations, followed by values in degrees. Use Keywords tx ty tz for translations, followed by values in angstroms. Use the Keyword center to center the coordinates at the origin. The transformation keywords and values can be separated by equal signs or commas for clarity, but this is optional. For example, the following two specifications are equivalent:
rx=35, ry=45, rz = 55, center
rx 35 ry 45 rz 55 center
