Project: pEFF

Version: August 2009
|
|
|
|
Usage: python VMD-input.py lammps_dump_filename radii_column_number
|
|
Example: python VMD-input.py dump.lammpstrj 6
|
|
|
|
1. Extracts the electron radii from a lammps trajectory dump into %s.out
|
|
2. Creates %s.xyz file
|
|
3. Creates appropriate %.vmd file which can be sourced using TCL/TK in VMD
