LattUtil

Utility for handling VASP structure file

This is a utility program for handling VASP structure file (i.e. POSCAR).

List of capabilities:

1. Find and display the symmetry of the system (info of space group, etc.)
2. Regulate the structure with a fine precision
   (this is sometimes useful since the output of some software is only in single float prec).
3. Re-define the lattice (you may use this function to build a supercell)

Note 1

LattUtil relies on spglib (later than 1.11) and armadillo, you need to compile these two libs before compiling LattUtil.

Note 2

LattUtil employs regular expression to handle text files,therefore you need a relatively later version of gcc (later than 4.9).
