The scripts now handles the diagonalization itself via package fromĬPAN. That were calculated in their corresponding OUTCARs (see ). The DISPLACECARs should only contain those degrees of freedom Takes the output from the dynamical matrix calculation and creates the matrix. Output: mass-scaled dynamical matrix (freq.mat) Or : (#DISPLACECAR) (DISPLACECAR1) (DISPLACECAR2). Warning: this script does not give a set of equally spaced images. The new geometry is written in the POSCAR file, and the If atoms are closer than the specified distance, the script pushes these atoms apart. This is useful if you need to give all POSCARs in a NEB calculation the same frozen point. Takes an atom number and a list of POSCAR files and then freezes that atom, as well as shifting the contents of each POSCAR file so that thatĪtom has the same position in each cell. Output: spline.dat, neb.dat, exts.dat, mep.eps, movie.xyz, vaspgrĪfter a run has finished and wrapped up with, the can be used to run, , and Output: directory (vaspgr) with plots of energy and forcesĬan be used to monitor convergence for each image while the job is still running. The data in the neb.dat while exts.dat contains the location and energy of all extrema found along the curve and mep.eps is a plot of the MEPĬan be used to generate a movie from standard xyz files, generated either by POSCARs (flag=0) or CONTCARs (flag=1) in every directory. spline.dat is a set of points that describe the spline fitted to Reads the file neb.dat and creates the files spline.dat,exts.dat and mep.eps. Used by to generate a force-based cubic spline along the band. Generates the file neb.dat which contains the distance between images, the energy of each image, and the force along the band. Output: energy, distance, and forces along the neb Output: energy and force of images in the neb Curvature data from the MEP is used for the initial MODECAR. If no inputĪrgument is given then the run is set up by interpolation around the highest point in the exts.dat file. It is assumed that the configuration is contained in POSCARs, i.e. Output: directory saddle_lanczos containing files for lanczos run Curvature data from the MEP is used for the initial orientation of the DIMER. If no inputĪrgument is given then the dimer is formed by interpolation around the highest point in the exts.dat file. Output: directory saddle_dimer containing files for dimer run Written to the directories 00 to NI+1, where NI is the number of specified images. Takes initial and final POSCAR files, and linearly interpolates the specified number of images between them. Output: directories containing initial NEB POSCAR files Usage: (POSCAR1) (POSCAR2) (number of images, NI) Output: unit vector between POSCAR files, to MODECAR file Output: root sum squared distance between configuration files Output: distance between atoms, scalar and vector sum, to STDOUT Output: neighbor distances from a specified atom, to STDOUT Output: radial distribution around specified atom, to STDOUT Output: POSCAR with specified lattice constant In the run directory CONTCARs are moved over POSCARs in preparation for a new run. OUTCAR (zipped), INCAR, KPOINTS, XDATCAR (zipped), CHGCAR and WAVECAR if the are non-empty) are copied to the output directory. ![]() This script finds the ICHAIN tag from the OUTCAR and cleans up the run directory accordingly. Prints the force and energy at each iteration of a vasp run. POSCAR file, reading and writing a generic vector file, doing dot products and finding magnitudes of vectors and other similar functions Perl module that contains various common commands that one might want when deal with VASP POSCAR files.
