Create a VASP CHGCAR file from a JDFTx output file. Usage: createVASP <jdftxOutFile> <vaspFile> [<nFilename>] Save the final structure and electron density from JDFTx output file <jdftxOutFile> to a VASP CHGCAR format file in <vaspFile>. The electron density is read from the appropriate filename determined by parsing the output; this can be overriden by explicitly specifying <nFilename>. Note: this tool requires awk and octave to be available in path.
