the two files you are mentioning will be created automatically by the kinematic optimzation in AnyBody. They contain information about the calculations and also the new marker coordinates. If new segment lengths have been calculated these are included as well. You can just open them with a usual text editor to get an understanding. You will see that only the parameters that you chose to be optimized will be included (which makes sense…).
For above model file, I don’t know what your intention is.
I think that Patrick explained well about the purpose of those text files.
And if you want to know more detail about how those text files could be created,
then you have to see ‘Sequence1.anymcr’, ‘SaveMacroOperation-Save.anymcr’, ‘RunMacroOperation-Save.anymcr’ files.
The reason is that RunMotionAndParameterOptimizationSequence operation is like this:
