I find an ERROR of the ground truth pose processing!

Hi,
Thank you for sharing this wonderful work!
A lot of the current registration works follow your evaluation metrics. However, I recently find an error in "data_loaders.py". The line 467 "M2 = M @ reg.transformation" should be "M2 = reg.transformation @ M". I have done several tests and am pretty sure of this. Could you check this and tell if it is right.Thanks!

in open3d, PointCloud.transform(transformation) means transformation @ PointCloud

Definitely, so M2 should be calculated as transformation @ M. 施成浩 ***@***.***
