About mapping between original AIST and AIST in motionx

[thyzju17]

In motionx, the dance motions are renamed with 'Dance_Break_3_Step', 'Dance_Break_Cc', and 'Dance_Break_Roll_Two_Step', etc.
However, in original AIST dataset, genre('Beak'), dancer ID, music ID, and Choreography are given, instead of the '3_Step', 'Cc', and 'Roll_Two_Step'.
The mapping between the name style of original AIST and AIST in motionx is not clear. How to get the mapping?
