Hi,
during the calculation of a Barry's phase with IGPAR=3 received a couple of time the following WARNING:
------------------------------------------------------
Im ln[Det|M_k|/<Det|M_k|>_av]= 2.52818 <= WARNING: larger than pi/2, not well clustered.
--------------------------------------------------------
I'm doing this on a slab with a polarization along [001] and the usual dipole correction.
The same calculation with IGPAR=1 gives another error:
--------------------------------------------------------
Error in subroutine BERRY: did not find all determinants
Matrix CMK is not an nxn matrix for
ISTR = 1 j = 0
--------------------------------------------------------
how can solve it?
thanks
