To map several molecules at once, put together the CONTCAR files (CONT*). Then use the attached scrip with xcrysden.
The script has three parts.
1. Convert POSCAR/CONTCAR to *.xsf
In order to use this tool, you will need the program v2xsf. Find attached here File:Xcrysden.tgz or here [[1]]. First, put v2xsf in your /home/bin/ folder and make it executable (chmod +x v2xsf). Then, put all your CONTCAR/POSCAR in the same folder with the extension *.vasp and execute the following command in a terminal:
for j in `ls *.vasp` ; do v2xsf $j ; done
2. Script preparation
XCrysDen can work with a *.tcl script as input file. This utility will build that script for you:
#!/bin/bash
# # # # # # # # # # # # # # # # # # # # # # # # #
# Created by Rodrigo García-Muelas #
# #
# Suitable for VASP 5.x #
# First review: July 10, 2012. #
# Second review: April 30, 2013. #
# # # # # # # # # # # # # # # # # # # # # # # # #
#
# Notes:
# 1. The input files should be *.vasp
# 2. Requires v2xsf conversor <--- Available on VASP webpage.
# 3. Inspired by a similar creation from David Karhanek.
# 4. Remember to write in the terminal: for j in `ls *.vasp` ; do v2xsf $j ; done

Explanation:
You can set the size of the window with the command below. Notice that a bigger window size imply a larger and heavier image.
scripting::displayWindow resize 800 1000
You can change the colors of your atoms. The example shows H, C, O and Pt (Z=1,6,8,78) and colors white (1.00 1.00 1.00 RGB), gray, red and light green:
xc_newvalue .mesa 8 1 1.000000 1.000000 1.000000 xc_newvalue .mesa 8 6 0.250000 0.250000 0.250000 xc_newvalue .mesa 8 8 1.000000 0.000000 0.000000 xc_newvalue .mesa 8 78 0.800000 1.000000 0.800000
To change the size of the ball for each element, you have this part:
xc_newvalue .mesa 4 1 0.90000 xc_newvalue .mesa 4 6 2.05000 xc_newvalue .mesa 4 8 1.80000 xc_newvalue .mesa 4 78 3.55000
To colour the borders of the supercell in black:
set myParam(FRAMECOL) {0.00 0.00 0.00}
Set the background color as white to be printer-friendly.
set myParam(BACKGROUND) {1.00 1.00 1.00}
Build a 1×1×1 supercell
scripting::buildCrystal 1 1 1
Play with these parameters in order to focus your cell at your wish:
scripting::rotate x 90 scripting::zoom 2
Do NOT put comments in the epsprinting.tcl file.
3. Printing and post-processing
Run XCrysDen in scripting mode by typing:
$ xcrysden -s epsprinting.tcl
Tips:
- If you want to convert the background of an image from white to transparent, write in the command line:
convert -transparent white <input_file> <output_file>
- If you want to crop transparent spaces, write in the command line:
convert -trim <input_file> <output_file>
- In batch mode:
for j in *.png ; do convert -transparent white $j $j ; done for j in *.png ; do convert -trim $j $j ; done
- Also it would work:
for j in `ls *.png` ; do convert -transparent white $j $j ; done for j in `ls *.png` ; do convert -trim $j $j ; done
- If you generated your figures in other formats (i.e. *.eps), and you want to convert them into png:
for j in *eps ; do convert $j ${j%%.eps}.png ; done
