-======Projects======
+======PiGMo10======
-A folder with subfolders which includes a set of xml-files to describe what to do with a dataset (session, a set of trials, typcially with c3d-files) is called a "Project". There are some projects specific for the Heidelber Motionlab.
-=====PiGMo10 Vicon PiG based=====
-This is a clone of what the PiGMo10 "modelscript" in **MoMo** calculates, based on the Vicon PiG model.
+This is a clone of what the PiGMo10 "modelscript" in **MoMo** calculates, based on the Vicon PiG model. So the complete pipeline from the raw data, to the sheets and to the exported hd-asc files used bei HeiDataProVIT is possible to substitute **MoMo**. Only some testing and finetuning to make the pipeline more robust is need for daily usage.
+======Gait with functional centers/axes======
-So the complete pipeline from the raw data, to the sheets up to the exported hd-asc files, used by **HeiDataProVIT**, is possible and can substitute **MoMo**.
+This projects add functional center/axes determination to the default Vicon PlugInGait model. It works together with the old **Vicon Workstation** and also with new new Vicon **Nexus system**.
-Extensive testing and finetuning is needed, to make the pipeline more robust for daily usage. Also some parameters MoMo saves in the hd-asc files are missed. It has to be checked if they are needed and if so determining of these parameters must be implemented.
+Additional to the ScoRE/SARA functional method implementation of Vicon several mathematical methods are available and the phases, which are used as input for the estimation, can be controlled by setting of events in the dynamic calibration trials.
-The lower body kinematics angles of this project are described [[http://nimue-platform.motion-science.org/doku.php?id=analysistools:conventionalgaitmodels|here]].
+To process the data specific dynamic calibration trials must be done and its specific eclipse entries must be set:
-=====PiGMo10 independent=====
-Additional to the above this also includes a Vicon PiG kinematics clone. This makes the project completly independent from Vicon codebase, for full flexibility.
-=====PiG with functional centers/axes=====
-This project adds functional center/axes determination to the default Vicon PlugInGait model. It works together with the old **Vicon Workstation** and also with new Vicon **Nexus system**.
-Additional to the SCoRE/SARA functional method implementation of Vicon, several mathematical methods are available and the phases, which are used as input for the estimation, can be controlled by setting of events in the dynamic calibration trials.
-====Eclipse entries====
-To process the data, specific dynamic calibration trials must be done and its specific eclipse entries must be set:
 ^ Name ^ Value ^ Description ^
-^ CLASS | Static_Cal | Static standing trial, typically used with knee alignment device. |
+^ CLASS | Static_Cal | Static standing trial, typically used with knee alignment device |
-^ CLASS | HipCircle | Optional, if HipFlex/Ext and HipAbd/Add are both available. |
+^ CLASS | HipCircle | |
-^ CLASS | HipFlex/Ext | Flexion/Extention of the hip, which should cause also flexion/extention of the knee; last is used for knee-axis estimation; so it is important, that in this trial also the knee is flexed at minim of 30 degrees RoM. |
+^ CLASS | HipFlex/Ext | |
-^ CLASS | HipAbd/Add | Optional, if HipCircle and HipFlex/Ext are both available. |
+^ TYPE | PiG, PiGFunctional | Indicates if the trial is processes with PiG or with functional PiG (Vicon implementation of SARA and ScoRE |
-^ TYPE | PiG, PiGFunctional | Indicates, if the trial is processed with PiG or with functional-PiG (Vicon implementation of SARA and ScoRE). |
 ^ SIDE | Side R, Side L, bds | |

-====Modelparameter files====
-Modelparameter-files are needed to read parameters from clinical measurements, which are used to define offset angles in the kinematics model.
-There is an important limitation in the mechanism to work with these files: You can have an mp-file only for each session and not for each group. That is why the mp-files are found only, if they are saved in the session and not in the group. Details of working with .mp-files and its limitations you can find [[http://nimue-platform.motion-science.org/doku.php?id=glue:vicon&#mp-files|here]].
-Used parameters are:
-<code>
-$LKneeWidth = 103
-$LAnkleWidth = 71
-$LTibialTorsion = -15
-$RKneeWidth = 104
-$RAnkleWidth = 71
-$RTibialTorsion = -15
-</code>
-=====PiG with functional knee joint axes only =====
-This project adds functional knee joint axes determination (SARA) only to the default Vicon PlugInGait model. It works together with the old Vicon Workstation system and allows to control the usage of the motion phases which are used for the estimation by setting of events.
-In the gait trials the lateral knee markers are projected onto the functional knee joint axes and the knee joint center is determined based on the clinical measurement of the knee width. Than the femur coordinate system is constructed equivalent to the original PiG. Keep in mind that this coordinate system does not have the functional axis as one of its axes. The axes are defined by cross products and have the longitudinal femur axes included.
-==== Preconditions ====
-  * It is assumed, that the Vicon PiG is processed for the static calibration trial and all gait trials, before processing with this model. Vicon PiG processing is not needed for the dynamic calibration trials.
-  * Additional markers on the shank are needed. Have a look at the follwing markerset picture
-  * Specific dynamic calibration movements with knee flexion; events to define the phases used by the estimation.
-  * Specific eclipse entries. Have a look at the following table and screenshot.

-====Eclipse entries====
-To process the data, specific dynamic calibration trials must be available and its specific eclipse entries must be set:
-^ Trial ^ Name ^ Value ^ Description ^
-^ 1 |  CLASS | Static_Cal | Static standing trial with knee alignment device. |
-^ 2 |  CLASS | HipFlex/Ext | Flexion/Extention of the hip, which should cause also flexion/extention of the knee; last is used for knee-axis estimation; so it is important, that in this trial also the knee is flexed at minimum of 30 degrees RoM. |
-^ all trials | SIDE | Side R, Side L, bds | Hip/Flex/Ext trials are typically unilateral, gait trials are typically bilateral |
-^ 3-n | CLASS | Dynamic or Dynamic+Kinetics | Trial with gait, Strides defined by events. |
