Category STRUCT_NCS_OPER

Name:
'struct_ncs_oper'

Description:

   Data items in the STRUCT_NCS_OPER category describe the
   noncrystallographic symmetry operations.

   Each operator is specified as a matrix and a subsequent
   translation vector. Operators need not represent proper
   rotations.

Example:

Example 1 - based on laboratory records for the protein NS1.
