SkyTEM response

HI, I am new to SimPEG. I want to generate 1D forward simulation for skytem system. I am using plot_fwd_1_em1dtm code for forward simulation. However, I am confused about how to put skytem geometry and waveform in this code.
I even tried to look at plot_booky_1D_time_freq_inv file…but this shows an error while running.
Can anyone please share how should I proceed with this. If there are any tutorial or module how to simulate forward response for skyTEM data.
Thanks in advance !!
