[phenixbb] centered triclinic lattice

Looking for suggestions — cctbx/phenix seems not to be able to handle a triclinic lattice with centering. Specific Example: PDB entry 1LKS with cell parameters/space group “A 1”: CRYST1 31.970 65.080 27.250 94.57 111.56 82.98 A 1 2 A 1 diagram: http://img.chem.ucl.ac.uk/sgp/large/001bz1.htm http://img.chem.ucl.ac.uk/sgp/large/001bz1.htm Are there any other options for working with this data in phenix other than creating an explicit 2nd copy of the coordinates at x, 1/2+y,1/2+z and setting space group to primitive lattice P 1? Thanks in advance.
