Alert level B PLAT420_ALERT_2_B D-H Without Acceptor O3 - H3A ... ?
Alert level C PLAT906_ALERT_3_C Large K value in the Analysis of Variance ...... 3.016
Alert level G REFLT03_ALERT_4_G ALERT: MoKa measured Friedel data cannot be used to determine absolute structure in a light-atom study EXCEPT under VERY special conditions. It is preferred that Friedel data is merged in such cases. From the CIF: _diffrn_reflns_theta_max 25.00 From the CIF: _reflns_number_total 2866 Count of symmetry unique reflns 1680 Completeness (_total/calc) 170.60% TEST3: Check Friedels for noncentro structure Estimate of Friedel pairs measured 1186 Fraction of Friedel pairs measured 0.706 Are heavy atom types Z>Si present no PLAT002_ALERT_2_G Number of Distance or Angle Restraints on AtSite 4 PLAT005_ALERT_5_G No _iucr_refine_instructions_details in the CIF ?

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