Code:

NAME
pwo2xsf - convert the pw.x output file to XSF format SYNOPSIS
pwo2xsf [special-option] coordinates-option [file] DESCRIPTION
pwo2xsf extracts atomic structures from pw.x output 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.xcrys- den.org/doc/XSF.html). If file is not specified then standard input is read. SPECIAL OPTION
-r dim Reduce periodic dimension to dim, i.e., dim = 2, 1, or 0. COORDINATES OPTIONS
These options specify which cordinates to extract. The possibilities are: -ic file --inicoor file Extract the initial, that is, input ionic coordinates. -lc file --latestcoor file Extract the latest printed ionic coordinates from pw.x output file. -oc file --optcoor file Similar to "--latestcoor" but extracts just the optimized coordinates if present or else nothing. -a file --animxsf file Extract the coordinates of all ionic steps as Animated-XSF. -nc file --nebcoor PW.out Extract the coordinates and forces from the PW.out file of NEB (path) calculation.
