+====== Modify One Force Platform ======
+This command can be used to perform the same function as the [[visual3d:documentation:pipeline:force_commands:modify_force_platform_parameters|Modify Force Platform Parameters]] command, but for just one force platform.
+====Pipeline Command====
+This command can be found in the Pipeline Workshop within the **Force** folder as so:
+<code>
+Modify_One_Force_Platform
+! /FP_SELECTED=
+! /FP_TYPE=
+! /FP_CHANNEL=
+! /FP_ORIGIN=
+! /FP_CALMATRIX=
+! /FP_ZEROS=
+! /FP_CORNER1=
+! /FP_CORNER2=
+! /FP_CORNER3=
+! /FP_CORNER4=
+! /FP_COP_POLYNOMIAL=
+! /FP_COP_TRANSLATION=
+! /FP_COP_ROTATION=
+! /UPDATE_C3D_FILE=FALSE
+! /MODIFY_CAL_FILE=FALSE
+;
+</code>
+====Command Parameters====
+The following table shows the command parameters seen above and their descriptions:
+|**FP Selected**|Which force platform to be modified|
+|**FP Type**|Types of force platforms (1=default, 2= AMTI,Bertec, 3= Kistler)|
+|**FP Channel**|An array containing the ANALOG channels associated with the force platform|
+|**FP Origin**|The origin of the force platform in the force platform coordinate system (see the force platform manufacturer specifications|
+|**FP Calmatrix**|This section allows the user to manually enter the force plate calibration matrix. This matrix is individual to force plate|
+|**FP Zeros**|The zero start and zero end, specific for each force plate|
+|**FP Corner**|The (x,y,z) coordinates of the force platform corners in the laboratory coordinate system. Note that there is a [[visual3d:documentation:pipeline:force_commands:fp_corners|specific ordering of the four corners]]|
+|**FP COP Polynomial**|The polynomial describing the COP|
+|**FP COP Translation**|The translation applied to the COP|
+|**FP COP Rotation**|The rotation applied to the COP|
+|**Update C3D File**|True or False: Update the existing c3d file to the new parameters|
+|**Modify Cal File**|True or False: Modify the calibration file to the new parameters|
+====Dialog====
+It is also possible to modify force platform parameters via the graphical interface's dialog located in Visual3D's Force menu. The dialog provides you with an overview of all the current force platform parameter values and allows you to edit and save these values.

+====Example: Vertically Shifting Each FP Corner====
+This example shows how the each corner of a force platform can be given a vertical translation:
+<code>
+Modify_One_Force_Platform
+/FP_SELECTED=1
+/FP_TYPE=2
+/FP_CHANNEL=1+2+3+4+5+6
+/FP_ORIGIN=241.5+819+-0.001
+! /FP_CALMATRIX=
+/FP_ZEROS=1+0
+/FP_CORNER1=-1.502+-819.00098+0.
+/FP_CORNER2=-484.50195+-818.99896+0.
+/FP_CORNER3=-484.49799+819.001+0.
+/FP_CORNER4=-1.498+818.999+0.
+/FP_COP_POLYNOMIAL=0+0+0+0+0+0+0+0+0+0+0+0
+/FP_COP_TRANSLATION=0+0+0
+/FP_COP_ROTATION=0+0+0
+! /UPDATE_C3D_FILE=FALSE
+! /MODIFY_CAL_FILE=FALSE
+;
