[Pw_forum] doing QHA calculations

[Tuhina Kelkar]

Hi everyone!
First of all thanks to all those who gave me their inputs on phonon dispersion calculations. I am having another problem now. 
After calculating the Phonon DOS for MgH2 at different alat values when I run fqha.x I get the following message everytime "wrong grid" and the program stops. What does it mean by wrong grid and how do I correct this error?
Please reply asap. Thanks in advance.
