Issues understanding the input format for eth_ucy

[to314as]

Dear reader, thank you for the great work on this topic and for realising the code for the community to improve. I am currently trying to understand the data format however am very unclear about how the eth_ucy dataset is actually preprocessed. Do I understand it correctly that only x and y coordinates are used and no velocity and heading inofmration is extracted. As looking through the data most columns only contain -1 values. Could you provide a column name list for the inputs found in the datasets/eth_ucy files?

Furthermore, is my understadning correct that only the ego agent informatin is stored in a given row? As from reading the paper my understanding was that all agent states would be stored in a single entry for each timestep. Could you maybe elaborate on how you create the representation of the data that is described in the paper? Thank you!
