Alert level C PLAT250_ALERT_2_C Large U3/U1 Ratio for Average U(i,j) Tensor .... 2.9 Note PLAT906_ALERT_3_C Large K value in the Analysis of Variance ...... 4.152 Check PLAT911_ALERT_3_C Missing # FCF Refl Between THmin & STh/L= 0.600 2 Why ?
Alert level G PLAT005_ALERT_5_G No _iucr_refine_instructions_details in the CIF Please Do ! PLAT007_ALERT_5_G Number of Unrefined Donor-H Atoms .............. 1 Why ? PLAT063_ALERT_4_G Crystal Size Likely too Large for Beam Size .... 0.65 mm PLAT066_ALERT_1_G Predicted and Reported Tmin&Tmax Range Identical ? Check
0 ALERT level A = Most likely a serious problem - resolve or explain 0 ALERT level B = A potentially serious problem, consider carefully 3 ALERT level C = Check. Ensure it is not caused by an omission or oversight 4 ALERT level G = General information/check it is not something unexpected 1 ALERT type 1 CIF construction/syntax error, inconsistent or missing data 1 ALERT type 2 Indicator that the structure model may be wrong or deficient 2 ALERT type 3 Indicator that the structure quality may be low 1 ALERT type 4 Improvement, methodology, query or suggestion 2 ALERT type 5 Informative message, check
