wot trajectory :Empty population list

[annrosebright]

Hi, I am trying to run wot on the simulated data provided with the tutorial. But i keep getting this error. Can you please help on why this error is occurring. I wanted to first run the commands on this dataset and apply it on our dataset.

wot trajectory --tmap tmaps --cell_set cell_sets.gmt --time 10 --out traj.txt
