Hi Experts, 

I am new cp2k user. I am trying to simulate a MD simulation on a metallic 
alloy and it keeps failing to start a NPT MD. I have a question about the 
structure boundaries in CP2K. I created the initial box in lammps and 
visualizing in ovito. Below are the box sizes. Am I converting it correctly 
for the cp2k simulation. 

*# LAMMPS data file written by OVITO*
208 atoms
3 atom types
-0.104644 20.6326618 xlo xhi
-19.8380928 19.8555032 ylo yhi
-0.0701645 2.082567 zlo zhi

*! CP2K Format*
