[Pw_forum] NaN values for Tc calculations

[Bahadir Altintas]

I have some problem in calculation of Tc of a system with spacegroup 166 
(LiH_6).

1. By adapting the example07 to my system, I tried to calculate Tc but I 
got NaN values for both omega_log and T_c values in lambda.out also all 
values are NaN in alpha2F.dat

In my calculation: there is no problem with phononDos btu i can not be 
able to get any values for Tc. i am really confused.

P.S: there is no problem for Tc calculations of Li-fcc structure.

thanks if anyone has any suggestions
