Installation: The package is installed by distutils: ie. python setup.py install # default python setup.py install --prefix=PREFIX_PATH # package installed PREFIX_PATH Setup: PATH and PYTHONPATH is setup, when package installed PREFIX_PATH ie. # for sh/bash export PATH=PREFIX_PATH/bin:$PATH export PYTHONPATH=PREFIX_PATH/lib/python2.6/site-packages # for csh/tcsh set path=(PREFIX_PATH/bin $PATH) setenv PYTHONPATH PREFIX_PATH/lib/python2.6/site-packages Command: The some commands are supported convert between VASP POSCAR and gaussian input. v2g.py is converted tool, supports VASP input (POSCAR) to tranform to Gaussian input (.gjf or.com). Usage: v2g -i POSCAR -o xxx.gjf -h : help -i : input file, ie POSCAR -o : output file, ie xxx.gjf, xxx.com ie. v2g -i POSCAR g2v.py is converted tool, supports Gaussian input (.gjf or.com) to tranform to the VASP input (POSCAR). Usage: g2v -i xxx.gjf [-o POSCAR] -h : help -i : input file, ie xxx.gjf, xxx.com -o : output file, ie POSCAR ie. g2v -i xxx.gjf vscan.py is a tool to generate many image for VASP scan job. It needs POSCAR to be input and supports linear, angle and dihedral angle scan function. Usage: vscan.py ie. vascn.py
