Hello

I need some help.

Could anyone tell me what does the x value represent in the force_length_curve for the definition of Ligament in the Opensim (as shown below)? Thanks in advance.

<SimmSpline name="force_length_curve">
<x> -5 0.998 0.999 1 1.1 1.2 1.3 1.4 1.5 1.6 1.601 1.602 5</x>
<y> 0 0 0 0 0.035 0.12 0.26 0.55 1.17 2 2 2 2</y>
</SimmSpline>
