post-processing problem

[luebelue]

Hi! VFS is a wonderful software package.
But I encountered a problem, when I execute the "data" file, no post-processing file is generated.
And the printed information is
[
nv_once=0
Begin Reading xyz.dat !
Finish Reading xyz.dat !
read coord!
PIn 2.261225e-01
]
How to get the post-processing file correctly?
