Convert the pw.x input file to xsf format
pwi2xsf [-r] file
pwi2xsf extracts the atomic structure from pw.x input file and prints the XSF formated structure data to standard output. It is a utility program of xcrysden package (http://www.xcrysden.org/) and XSF is the native xcrysden structure format (http://www.xcrysden.org/doc/XSF.html).
If file is specified as "-" then standard input is read.
-r
For old pw.x versions < 1.2 one must spefify the ityp-->nat conversion and the corresponding data are writen to file nuclei.charges. The -r flag deletes this file as to force new ityp-->nat specification.
