Database Question

[2447108258]

Dear limsim team, I was using limsim and opened the database db file. I noticed that the raw value of frameINFO is negative. Does this mean it is measured clockwise starting from the x-axis? Also, x and y should be the x and y axes in a Cartesian coordinate system, right? One more question: the collision value in evaluationINFO seems a bit strange. In the visualization interface, I can see a collision, but the output result is 20.
