Generate figures

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

If you are working with surfaces, you may want to eliminate the bottom layer before that. This example is for (111) metals with 2sqrt(3)×2sqrt(3) symmetry.

for j in `ls *.vasp` ; do sed -i "7s/48/36/g" $j ; sed -i "10,21d" $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

#
# 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
#
# remove old tcl scripts (this section needs to be fix)
if [ -e epsprinting.tcl ] ; then echo "removing old epsprinting.tcl" ; rm -f epsprinting.tcl ; fi
#
# comprobates if you have *.xsf.gz files
if [ -z `ls *.vasp.xsf.gz` ] ; then 
echo "Please execute: "
echo "for j in \`ls *.vasp\` ; do sed -i "7s/48/36/g" \$j ; sed -i "10,21d" \$j ; done"
echo "for j in \`ls *.vasp\` ; do v2xsf \$j ; done" 
echo "All your POSCAR's should have .vasp extension"
exit
fi 
#
# Note: you can use: "resize 640 480" or "resize 800 1000" or "resize 640 480", etc. Limit around 4000.

echo "Now run XCrySDen in script mode: xcrysden -s epsprinting.tcl"

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

The quality of the texture can be adjusted with the tessellation factor. Use low values (20) for fast screening, tests, and images of internal use. Use large values (99) for publication-quality images.

set myParam(TESSELLATION)      20.00

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>

• If you want to crop the side view images, do:

convert -gravity Center -crop 120x30%+0+100\! <input_file> <output_file>

• You can also do ("x" and "y" directions, + for right/up , - for left/down:

convert -crop +0-275 <input_file> <output_file>

• In batch mode:

for j in *.png ; do echo $j ; convert -transparent white $j $j ; done
for j in *.png ; do echo $j ; convert -trim $j $j ; done
for j in *.png ; do echo $j ; convert -gravity Center -crop 120x30%+0+100\! $j $j ; done

• It would also work:

for j in `ls *.png` ; do echo $j ; convert -transparent white $j $j ; done
for j in `ls *.png` ; do echo $j ; convert -trim $j $j ; done
for j in `ls *.png` ; do echo $j ; convert -gravity Center -crop 120x30%+0+100\! $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 echo $j ; convert $j ${j%%.eps}.png ; done
 for j in *eps ; do echo $j ; convert -density 600 $j ${j%%.eps}.png ; done
