PLAT180_ALERT_4_G Check Cell Rounding: # of Values Ending with 0 = 3 PLAT791_ALERT_4_G Note: The Model has Chirality at C1 (Verify) S PLAT791_ALERT_4_G Note: The Model has Chirality at C3 (Verify) R PLAT791_ALERT_4_G Note: The Model has Chirality at C8 (Verify) R PLAT909_ALERT_3_G Percentage of Observed Data at Theta(Max) still 89 %
1 ALERT level A = Most likely a serious problem - resolve or explain 3 ALERT level B = A potentially serious problem, consider carefully 2 ALERT level C = Check. Ensure it is not caused by an omission or oversight 6 ALERT level G = General information/check it is not something unexpected 0 ALERT type 1 CIF construction/syntax error, inconsistent or missing data 0 ALERT type 2 Indicator that the structure model may be wrong or deficient 7 ALERT type 3 Indicator that the structure quality may be low 4 ALERT type 4 Improvement, methodology, query or suggestion 1 ALERT type 5 Informative message, check
