Meaning of sequence_length in learn to simulate

[Xujxyang]

Thank you very much for providing excellent datasets in Learning to Simulate.
However, I have some questions regarding the variables in the metadata. Why is the value of sequence_length smaller by 1 compared to the actual dimension of the variables in the data? For example, in the waterramps dataset, the sequence_length is 600, while position.shape[1] is 601.

Excuse me, can you share the datasets?
