Why is there a mismatch in no. frames bettween .npz and json files

[yunhanwang1105]

Hi, thank you for your great work.

I found there is a mismatch in no. frames bettween .npz and json files

For example, in CIRCLE_movement/s2/bathroom1_lights_1_bathroom1/0/000_transition/vr_data.json
The length of "data" is 1117,
While in
CIRCLE_movement/s2/bathroom1_lights_1_bathroom1/0/000_transition/000_transition.npz
The length of 'poses' is 1146.

I also found this problem in other data samples. Could you please explain why there is such a mismatch, and can we safely use the goal frame indicated in the JSON file?

Thank you in advance.

Best.
