CheckCIF-REFLT01

PROC-NAME: REFLT01 Type_1

PURPOSE: To check that _reflns_number_total is less than or equal to the _diffrn_reflns_number.

PROCEDURE:

TEST

IF _reflns_number_total > _diffrn_reflns_number

issue ALERT B

   "Alert B The number of symmetry-independent reflections cannot exceed the total number of reflections measured"

The total number of reflections measured originally by the diffractometer should be given under _diffrn_reflns_number. Any subsequent set of reflections derived from this must, logically, be a subset of the total reflections measured. Therefore, the reported number of unique reflections given with _reflns_number_total must be less than (or possibly equal to) the number given under _diffrn_reflns_number. Check for typographical errors.

例：REFLT01_ALERT_1_B The number of symmetry-independent reflections cannot

            exceed the total number of reflections measured

            Number of symmetry-independent reflections = 10384

            Total number of reflections                =  10383

警告原因：_reflns_number_total值大于_diffrn_reflns_number。

解决策略：一般不会出现，可能是误操作，将其改正。
