UT theoretical chemistry code forum

I have a question of These two scripts, from the Website, I think both These two scripts can describe the distance between two POSCAR, and the results of dist.pl is the vector value in the result of diffcon.pl.
For example, when I optimized a configuration or before a NEB calculation, I use dist.pl like 'dist.pl POSCAR CONTCAR' or 'dist.pl POSCAR1 POSCAR2', if the vector value is larger, does this means the configuration have an obviously deforamation during the optimization or the Initial configuration quite different to the final configuration?

Yes, a large (vector) distance between two images does indicate a significant geometry change.

thanks for your reply!
