<div>Dear all,</div>
<div> </div>
<div>I am using NEB to calculate the adatom diffusion barrier on metallic surface.</div>
<div> </div>
<div>Do I need to relax the first and last image in separate calculations before writing the input file for NEB calculation with intermediate images? Or can be done automatically in single NEB file? What is the criteria for convergence? (i.e. is it the third column of output file (image energy(eV) <strong>error(eV/A)</strong> fronze) ?</div>
<div> </div>
<div>regards</div>
