====== Import Analog NDI Signals ======

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
! /C3D_FILE_NAME=
! /IMPORT_FILE_NAME=
! /UPDATE_C3D_FILE=FALSE
! /REPLACE_EXISTING_SIGNALS=FALSE
! /DELETE_ALL_EXISTING_SIGNALS=FALSE
;
</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.
