Dear Abinit Users,
Good Morning.

I am getting the following error while analyzing the anaddb for my system

symdm9 : ERROR -

In blok 1 the following element is missing :

Action : add the required information in the DDB,
or modify your input file.

i am attching the log file and also the output of ddb file.

Thanks in advance

Dear Sanjeev,

are you sure you have include all perturbation directions? it seems that is the case...it is hard just to say if you do not include the input calculation
for the phonon calculation...
