The walkAll_120.mat file contains 60 trajectories, a 40 x 6 x 60 matrix. Those were NOT used in the benchmark paper. 

The n-th 6D-trajectory can be accessed in matlab via
  walkAll_120(:,:,n)

The exposure time was set to 1/3, the frame rate of the Vicon recording system was set to 120fps.

The Rotation and Translation are stored as followed: 
(r_x, r_y, r_z, x,y,z )=(rotation about x, rotation_y, rotation_z, right,forward, up )

with the axis as described in the paper, so roughly the y-axis is the optical axis, the z-axis is showing up to the ceiling, the x-axis is showing to the right (a right-handed coordinate system).

the 40x6x60 matrix of the walkAll_120.mat file was also saved as 60 .txt files, each containing a table of size 40x6 (separated with comma)
