Hi,

Just an other question from an other newbie: Did you used "mergeddb" on you derivative database ?

regards

PMA

Dear abiniters,

After perfoming the test about response functions (RF) calculations, I return to my system. But I got the follwing error information when combinning all DDB files produced from the first step calculations? How to solve this problem? I must add some calculations on other k-points? But checking the second lesson on RF2, I also find the nkpts from input DDB and transfer DDB are not equal to each other. I am a newbie of abinit code. Please give me some helps.

===============================
  read the input derivative database information
read     1 blocks from the input DDB

read the input derivative database number     2
compare the current and input DDB information
chki8 : ERROR -
  Comparing integers for variable  nkpt.
  Value from input DDB is        14 and
        from transfer DDB is        27.
  Action : check your DDBs.

leave_new : decision taken to exit ...
===============================

Regards,
C.H.
