problem dumping to cfg file

Hi,
I have a problem in dumping into cfg format it is showing the error :

does not look like Ju Li’s CFG format because it does
not have “Number of particles =” as its first line.

Here is my dump code from input file:

dump 37 all cfg 10 CuNano5.*.cfg id type xs ys zs id type c_ack

What does that mean ?

thanks
Vanu

Your cfg command worked just fine for me. Maybe you need to
re-install your AtomEye, or check if your script actually ran and
successfully generated cfg.
