 =====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.
+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.
+The proximal tibia (anatomical) coordinate systems are defined by PiG virtual markers.

+==== Output ====
+In the default configuration the output is written into ".glx"-files in the hd-asc file format besides the corresponding input c3d-files. These files are written only for the gait-trials.
+Hip- and knee-angles are saved to its corresponding PiG angles with the same names but based on the functional knee joint axes.
+^ Name ^ Description ^
+^ R/LKneeAngles | Cardan angles describing the knee motion based on functional knee joint axes corresponding to the equal named original PiG angles.  |
+^ R/LHipAngles | Cardan angles describing the hip motion based on functional knee joint axes corresponding to the equal named original PiG angles  |
+==== Process Log ====
+The logging output is shown in a seperate window typically shown at the buttom of the application. If this window is not shown you can reopen it by the corresponding action in the Windows-main-menu.
+The following picture shows a part of the logging output of processing a session. The messages in black are only for information. The blue ones are warning. If there are red ones, something is totally wrong.

+You can see Intervals of frames defined by start- and end-frame enclosed in "[ ; ]". In these intervals the calculation cauld not be done. Typically the origin of this are unlabled markers. You should go to Vicon Worstation to check this.
+The information about the differences between PiG and functional PiG, given as an direction cosine angle between the corresponding two knee joint axes is print in blue but typically there is nothing wrong. But you should always have a look at it. If the differences is hight you should think about if this can be correct.
