Regarding rotation and translation matrix in 3DMatch.pkl file

[pomo1144]

@ShengyuH Could you please let me know how you preprocessed the 3DMatch dataset to get the rotation and translation matrix for the pair of point clouds, that we use to evaluate and get the evaluation results? I am trying to evaluate on Redwood dataset where I have ground truth information but no rotation and translation matrix associated with each point cloud pair as we have in 3DMatch.pkl file.

Please help me out with this issue. That would be helpful for me to evaluate the predator model on the Redwood dataset as well.
