+====== Import Analog NDI Signals ======
-Imports NDI Analog signals from a V# or O# formatted file into an existing C3D file. If the Analog rate is not an integer multiple of the Point rate, the Analog data will be resampled.
+The **Import Analog NDI Signals** command can be used to import NDI Analog signals from a V# or O# formatted file into an existing C3D file. If the Analog rate is not an integer multiple of the Point rate, the Analog data will be resampled.
+====Pipeline Command====
+The command can be found in the Pipeline Workshop within the **File Open/Import** folder as so:
 <code>
 Import_Analog_NDI_Signals
@@ Line 13: / Line 15: @@
 </code>
+====Command Parameters====
+The following table shows the command parameters seen above and their descriptions:
+|**C3D_FILE_NAME** |Name of starting C3D file|
+|**IMPORT_FILE_NAME** |Name of NDI signal to be imported, if left blank user will be prompted to select one|
+|**REPLACE_EXISTING_SIGNALS** |True or False: Replace existing signals in the workspace|
+|**DELETE_ALL_EXISTING_SIGNALS** |True or False: Deleting existing signals in the workspace|
+|**UPDATE_C3D_FILE** |True or False: Updated values in existing .c3d file|
+====Example: Replace values in existing C3D with those in NDI====
+The following code replaces existing values in a C3D file and replaces them with analog values in an NDI file:
+<code>
+Import_Analog_NDI_Signals
+ /C3D_FILE_NAME=Test_C3D
+! /IMPORT_FILE_NAME=
+/UPDATE_C3D_FILE=TRUE
+/REPLACE_EXISTING_SIGNALS=True
+! /DELETE_ALL_EXISTING_SIGNALS=FALSE
+;
+</code>
+====Notes====
 It is recommended that users [[Visual3D:Documentation:Pipeline:Plugins:Optotrak|translate the C# files into C3D files]], then import the analog files.
