P4V

go back to Main Page, Computational Resources, GUIS

P4VASP is a library for processing outputs from a VASP program (http://cms.mpi.univie.ac.at/vasp/Welcome.html) It is focussed mainly on the new xml output format, but it offers also limited support for some older formats (POSCAR, INCAR).

P4Vasp contains also an extensible GUI for visualisation and an api for (reasonably) easy creation of extension applets.

For people, who want to write just a simple script rather than an real applet, the easiest way to get informations from the vasprun.xml file is to use the XMLSystemPM class defined in p4vasp.SystemPM.
