Alert level C PLAT911_ALERT_3_C Missing # FCF Refl Between THmin & STh/L= 0.600 25 PLAT042_ALERT_1_C Calc. and Reported MoietyFormula Strings Differ ? PLAT912_ALERT_4_C Missing # of FCF Reflections Above STh/L= 0.600 32
Alert level G FORMU01_ALERT_1_G There is a discrepancy between the atom counts in the _chemical_formula_sum and _chemical_formula_moiety. This is usually due to the moiety formula being in the wrong format. Atom count from _chemical_formula_sum: C22 H24 F12 N6 O8 S4 Atom count from _chemical_formula_moiety:C20 H24 F12 N6 O8 S4 PLAT128_ALERT_4_G Alternate Setting of Space-group P21/c ....... P21/n
