Using the Adjective NOT
NOT can be used with the logical AND and logical OR
Example: Given a workspace containing 3 trials (*trial1.c3d, *trial2.c3d, and *trial3.c3d)
All trials are assigned a TAG labeled WALK
- trial1.c3d is also assigned a TAG labeled BAD
- Select_Active_File
- /FILE_NAME=WALK
- /QUERY=BAD
- ;
This command results in *trial1.c3d being active
- Select_Active_File
- /FILE_NAME=WALK
- /QUERY=NOT(BAD)
- ;
This command results in *trial2.c3d and *trial3.c3d being active.
equals
- = or == - Boolean Operator equals
Example: Comparing a model metric with a string
- Consider a model metric that is defined as a string.
- Set_Model_Metric
- ! /CALIBRATION_FILE=
- /METRIC_NAME=TEST
- /METRIC_VALUE="TTT"
- ;
- Now compare it to the text string "TTT"
- Evaluate_Expression
- /EXPRESSION=MODEL::METRIC::TEST="TTT"
- /RESULT_NAME=SCOTT
- /RESULT_TYPE=METRIC
- ! /RESULT_FOLDER=PROCESSED
- ;
- The text strings should be equal so the resulting signal contains a 1
