PLAT720 Type_4 Test for Unusual Labels

Up to 4 Character Labels of the type C11, H101, N10A, i.e. chemical symbol + number + optional letter are to be preferred.

(http://journals.iucr.org/services/cif/checking/PLAT720.html)

例：PLAT720_ALERT_4_G Number of Unusual/Non-Standard Labels ..........?????

警告原因：原子標(biāo)號不標(biāo)準(zhǔn)。

解決策略：將原子標(biāo)號改成Cu1類似格式，而不是Cu01，H0A等類似格式。

PLAT721 Type_1 Test for consistency of Bonds and Coordinates in CIF

Same as 701 but for distance without s.u. (esd). Difference is tested in terms of Angstroms.

(http://journals.iucr.org/services/cif/checking/PLAT721.html)

解決策略：幾個的話可以刪掉，如果很多的話，說明結(jié)構(gòu)解析有問題。

PLAT722 Type_1 Test for consistency of Angles and Coordinates in CIF

Same as 702 but for angle without s.u. (esd). Difference is tested in terms of Degrees.

(http://journals.iucr.org/services/cif/checking/PLAT722.html)

解決策略：幾個的話可以刪掉，如果很多的話，說明結(jié)構(gòu)解析有問題。

PLAT723 Type_1 Test for consistency of Torsions and Coordinates in CIF

Same as 703 but for torsion without s.u. (esd). Difference is tested in terms of Degrees.

(http://journals.iucr.org/services/cif/checking/PLAT723.html)

例：PLAT723_ALERT_1_C Torsion Calc 180(3), Rep 18.00 Dev

警告原因：扭角計算和報告值差值較大。

解決策略：多是由于無序處理后連通性有問題，在ins中處理后重新精修生成CIF。

PLAT724 Type_2 Test for consistency of Contact Distances and Coordinates in CIF

Same as 704 but for distance without s.u. (esd). Difference is tested in terms of Angstroms.

(http://journals.iucr.org/services/cif/checking/PLAT724.html)

警告原因：氫鍵中鍵長鍵角大小錯誤。

解決策略：修改ins中HTAB命令，重新生成cif文件。

PLAT725 Type_2 Test for consistency of H-Bond D-H distances and Coordinates in CIF

Same as 705 but for distance without s.u. (esd). Differences are tested in terms of Angstrom.

(http://journals.iucr.org/services/cif/checking/PLAT725.html)

警告原因：氫鍵中鍵長鍵角大小錯誤。

解決策略：修改ins中HTAB命令，重新生成cif文件。

PLAT726 Type_2 Test for consistency of H-Bond H..A Distances and Coordinates in CIF

Same as 706 but for distance without s.u. (esd). Differences are tested in terms of Angstrom.

(http://journals.iucr.org/services/cif/checking/PLAT726.html)

例：PLAT726_ALERT_2_A H...A?? Calc???? 8.92000, Rep???? 2.48000

警告原因：氫鍵中鍵長鍵角大小錯誤。

解決策略：修改ins中HTAB命令，重新生成cif文件。

PLAT727 Type_1 Test for consistency of H-Bond D..A Distances and Coordinates in CIF

Same as 707 but for distance without s.u. (esd). Differences are tested in terms of Angstrom.

(http://journals.iucr.org/services/cif/checking/PLAT727.html)

警告原因：氫鍵中鍵長鍵角大小錯誤。

解決策略：修改ins中HTAB命令，重新生成cif文件。

PLAT728 Type_1 Test for consistency of H-Bond D-H..A Angles and Coordinates in CIF

Same as ALERT 708 but for angle without s.u. (esd). Differences are tested in terms of Degrees.

(http://journals.iucr.org/services/cif/checking/PLAT728.html)

例：PLAT728_ALERT_1_A D-H..A Calc 66.00, Rep 131.03

警告原因：氫鍵中鍵長鍵角大小錯誤。

解決策略：修改ins中HTAB命令，重新生成cif文件。
