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

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.
