A series of pathological macromolecular crystallography datasets with twinning and other lattice disorders

These 11 datasets were collected at the Diamond Light Source and belong to the same protein, NAL (N-acetyl neuraminic acid lyase), which crystallised in 4 different crystal forms from the same crystallisation conditions producing crystals with the same morphology. The file names, where applicable (10/11 cases), contain the corresponding PDB deposition code.
