Does the datasets only provide the amplitude of CSI #14

Dear authors,

I want to implement some Wi-Fi sensing algorithms on the datasets provided by you. However, I found that only the amplitude of the CSI is provided in the datasets. (I only checked the UT-HAR and the NTU-Fi HAR) So I wonder is there a way to get the phase information of those datasets?

By the way, the CSI size of UT-HAR is 1 x 250 x 90. For other datasets, the size is (batch, antenna, subcarrier, packet). But according to the original paper of UT-HAR, 90 should be the number of subcarriers on 3 receiver antennas? I just want to make sure if all the datasets follow the size (batch, antenna, subcarrier, packet) or UT-HAR is different.

Thank you so much!
