[Mne_analysis] Conductivity 1 layer or 3

[Andrade Rey René]

        External Email - Use Caution        

Do you need me to show you the error or do you already have an idea of the issue that I have when doing the conductivity with 3 layers in bem model? I don't remember what it said but there was certainly an error stoping me from going further in the analysis. I used the numbers in conductivities from a tutorial in mne. I don't know if these numbers change and how to obtain them. 
Thanks!!

If I do 3 the output is an error if I choose 1 layer the output in forward solution is an error pointing to 3 layers in BEM model. What can I do?
