Hello
I am changing the Gaitlower Extremity Model to use it with a new Marker Set. Changing the sRelOpt isn’t a very straight forward method. I programmed that for a Matlab program where I can select graphically the Marker Point. After selection the calculation from the global coordinate system back to the segment CS is done by Matlab. vlocal = Axes0’*(vglobal-r0). To get the Segment stl I used the segment export function. And there is the problem: The stl file is a little different orientated in the AnyBody “Model View” than in this stl file. As a result the Marker Position is not congruent (See Picture). For example the Medial Epicondylus Marker on the Right Femur (see picture) is not congruent. See also the result from the Matlab calculation and the point itself in Geomagic.
Do you know why that could be?

I found the problem:
It is necessary to consider the ScaleMat. Than it works.
