Mathematical Operators

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
