Alert level B PLAT111_ALERT_2_B ADDSYM Detects (Pseudo) Centre of Symmetry ..... 94 PerFi
Author Response: The presence of pseudosymmetry in the structure suggests the higher symmetry space group <i>C</i>2/<i>c</i>, but attempts to refine the structure in this space group resulted in an unsatifactory model and high <i>R</i> and <i>wR</i> values.

0 ALERT level A = Most likely a serious problem - resolve or explain 2 ALERT level B = A potentially serious problem, consider carefully 12 ALERT level C = Check. Ensure it is not caused by an omission or oversight 10 ALERT level G = General information/check it is not something unexpected 2 ALERT type 1 CIF construction/syntax error, inconsistent or missing data 6 ALERT type 2 Indicator that the structure model may be wrong or deficient 8 ALERT type 3 Indicator that the structure quality may be low 6 ALERT type 4 Improvement, methodology, query or suggestion 2 ALERT type 5 Informative message, check
