[Pw_forum] Error while calculating Tc using Allen-Dynes formula

[pachineela rambabu]

Dear Forum, New year greetings to all.
                  After running lambda.x, I got the following output in
lambda.out:

Actually, I used spin-orbit coupling in my calculation. My lambda.in file
is:

Please tell me where am I wrong and how to get Tc?

thanks in advance,
