Question concerning start_frame and end_frame in index.csv

[he-nantian]

I am confused of the start_frame and end_frame stored in index.csv when running raw_pose_processing.ipynb.

Ideally, the length in pose_data should be 1/6 of the length of the corresponding data in amass_data cause it down-samples the motion from 120 to 20.

However:

• The amass data in amass_data/KIT/9/step_over_gap05_poses.npz has the length of 555 and the corresponding start_frame and end_frame are 0 and 111;

• The amass data in amass_data/KIT/3/bend_right05_poses.npz has the length of 515 and the corresponding start_frame and end_frame are 0 and 103.

The core issue is that after multiplied by 6, the indicated truncated length is larger than the original length, e.g., 666>555, 618>515. I wonder what information I am missing and wish to get the official response. Thanks!
