BASH – vasp2xyz, a script to extract coordinates from VASP

Users of VASP are often familiar with the struggles/hardships to easily visualize the coordinates from the output file OUTCAR. To that effect, I wrote the following script … with help at a crucial stage from Pat Krogel, Center for Experimental Computation at Michigan Technological University. It requires the OUTCAR and POSCAR files from a VASP simulation to be in the same folder and when successfully completed, it generates in – containing frame-by-frame XYZ coordinate information corresponding to each (optimization) step.

The script is part of a GitHub repository.


Well, some of you have been regular readers (and commentors) for my journal in this part of the e-world and such of those have known that I have been in Europe – J├╝lich, Germany – to be precise.
