'calc w=1/[\s^2^(Fo^2^)+(0.1000P)^2^+0.0000P] where P=(Fo^2^+2Fc^2^)/3'

JANA style weight is expected to be given in the format:

plaT930 Type_2 Test for Missed Twinning from FCF data

Check the proposed Twin Law. The entry in () represents the proposed rotation axis in reciprocal space and the one in [] the corresponding rotation is direct space. The relevant Twin Matrix can be found in the file '.ckf'.

Note: This analysis is based on Fo/Fc differences with Fc data given in the .fcf file (i.e. Fobs, Fcalc listing). ALERT-930 is expected to generate an related ALERT-931 as well.

例：plaT930_ALERT_2_B Check Twin Law ( 0 1 -1)[ 0 5 -2] Estimated BASF 0.17

警告原因：可能有孿晶存在。

解決策略：加入孿晶法則按孿晶精修，如果不行需重新還原數(shù)據(jù)并拆分。

孿晶，用platon找到twin law，然后加入res中精修。

如果不能解決，

1，當(dāng)platon分析twin law時，生成hklf 5格式的衍射數(shù)據(jù)，然后把res里hklf 4改成hklf 5，用新生成的hklf 5格式的衍射文件修。

2，重新做數(shù)據(jù)還原，用相應(yīng)的軟件找到孿晶的兩個domain，然后再積分?jǐn)?shù)據(jù)，這樣會得到兩個hklf 4衍射文件和一個hklf 5衍射文件，先用hklf 4的確定模型，然后用hklf 5的最后精修。

若用OLEX2，則可以在“Twinning”菜單欄(下圖所示)中使用“Search for Twin Laws”按鈕來尋找孿晶法則。
