Seebeck coefficient and importing relaxation time using mesh.file

Hi, kind users,
1.I have run amset according to the documentation, but when I wanted to reveal the image of Seebeck coefficient, it is represented like this, this is weird, I was wondering whether something is wrong here.

2.There is another question, I want to import the relaxation time in different specific scattering mechanism at one time. Is there any good way to realize that goal?
Your help would be highly appreciated.
Best regards!

It looks like you’re plotting both and n- and p-type carrier concentrations at once. You can select a specific doping polarity using amset plot transport --n-type for n-type transport or with --p-type for p-type transport.
