Volume 2 Chapter 7 Numeric Sub-menu *RFACTOR
*SIGFLAG is used to test for entries having a specified range of values of the average esd of C-C bond lengths.
CSD Contents
The average esd of C-C bond lengths in a structure is given a flag value corresponding to the range of values into which it falls. These flags can be searched using tests or screens.
The complete set of flag values is :
average sigma(C-C) not recorded 0 in range 0.001-0.005Å 1 in range 0.006-0.010Å 2 in range 0.011-0.030Å 3 greater than 0.030Å 4
Graphics QUEST3D Procedure
Select *SIGFLAG from the NUMERIC sub-menu and respond to the standard numeric prompts.
Basic QUEST Procedure
