On using anaddb, i got error message,
symdm9 : ERROR -
Informations are missing in the DDB.
The dynamical matrix number 27 cannot be built,
since no blok with wavevector 5.000000E-01 5.000000E-01 2.500000E-01
has been found.
Action : add the required blok in the DDB, or modify your input file.
Thanks

You have ndtset 10 but you have 12 input calculations to do (12 different qpt values); change ndtset to 12 and re-run (or just run the last two that you didn't run before and merge the DDB's in with the mrgddb utility).

Prof thanks alot. I will edit my input and re-run the file.

prof Josef and others,
Please help, i dont know how to edit the input file of band2eps. This is my frequency file,
