Issue with Using Sidebar Tools in VESTA

[Caleb Urbano]

Hello all!

I am a new user of VESTA on Windows, and while trying to measure some things in my structure (POSCAR titled GaN_332_Supercell.vasp attached), I have run into an issue where I can only select one atom when using the distance feature. The attached screenshot shows the Ga atom (green) selected, but when I click on a N atom (blue), I get the summary shown at the bottom. It seems like the program is measuring from the atom I clicked to that same atom (giving 0 Angstroms), despite me selecting other atoms.

I would like to understand what is causing this problem and if I am simply using the tool incorrectly. Any help would be greatly appreciated. Thank you!

All the best,

Caleb
