My goal is to use epw.x but when I was trying to first complete the ph.x
calculation I kept running into this error:
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
from tipo_sym : error # 1
symmetry not recognized
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
stopping ...
I checked the forum concerning this error but as expected the misplaced
parenthesis had been fixed in the 4.0.3 version (only using such an old version
b/c epw.x requires it). After encountering this error while testing an epw.x
example I tried a pwscf example02 that utilizes ph.x (from version 4.0.3; The
example shows how to use pw.x and ph.x to calculate phonon frequencies at Gamma
and X for Si and C in the diamond structure and for fcc-Ni.) and I received the
same error.
Any help would be much appreciated!
Thank you,
