Hi

Your "ifc.q2r" file is missing.

Please read the input file description with 'lifc' variable below;

Variable: lifc

Type: LOGICAL
Default: .false.
Description: If .true. uses the real-space inter-atomic force constant generated
by q2r.x. The resulting file must be named "ifc.q2r". The file has to be placed
in the same directory as the dvscf files.
In the case of SOC, the file must be named "ifc.q2r.xml" and be in xml format.
See asr_typ for the type of acoustic sum rules that can be imposed.

Best,
Hari Paudyal

Hi,

It looks like you are restarting your job with "wannierize = .true.". You need to set it ".false." and use your "prefix.ukk" file.

Best,
