How to determine exact energy values that good to plot in Seebeck vs Temperature?

[Kanij Fatima]

Good evening everyone. I am currently working on the research for the thermoelectric properties of the double perovskite structure. I'm using BoltzTraP to determine the thermoelectric properties and plot them using BoltzTraP_tools (python). I'm still a beginner in this software as per my question above I want to know how to choose the best energy for calculation?

But as you know from trace2. file (case.trace2) in BoltzTraP code there is a lot of energy list so I want to know how to choose among them?

For example - the picture shows the Seebeck as a function of E-Ef. So from the graph how are we going to determine which energy is good to plot for Seebeck as a function of Temperature. Here I attached the trace file, trace2 file, intrans file.

Thank you in advance!
