[Phonopy-users] Phonopy: ValueError: could not convert string to float: '*********'

[Raihan A. <rai...@in...>]

Hi,

I have performed phonon calculation in VASP using phonopy inputs for a
2x2x1 supercell. The VASP scf calculations converged normally. However,
when I try to create FORCE_SETS file using the command " phonopy -f
disp-{001..064}/vasprun.xml ", I get the following error-  *ValueError:
could not convert string to float: '*********' *

Please help with this issue.

[raihan@master 221]$ phonopy -f disp-{001..064}/vasprun.xml
