Some questions about the dataset pst.

[Einsturing]

Hi! Recently I try to use the dataset pst (2520 * 399, same as the paper) to run the code. But I can't get similar result as those in the paper. Maybe I made some mistakes.So I have some questions to ask you.
1.In the paper you said there are 8 relations in the dataset pst (north, east and so on), does this mean that I should generate 8 dir_relasiton.csv files correspond to the directions in the original dataset? What I'm using is a single file and W_{ij} is 1 if j is in one of these 8 directions of i, Is it wrong?
2.In the paper you said using size T to train and the evaluation of the quality of the model will be made over T + 1 to T + 5 time steps.Does this means, for example, if I use 0-200 to train, I should use 201-205 to test? Last time I used 201~399 to test, the result was a little bit awful.
I'm very sorry to disturb you again. I would appreciate it if you could reply to me. Thanks!
