<div>Hi All,</div>
<div> </div>
<div>I'm a new user of Xcrysden.</div>
<div>I have a question about the k-point generation using Xcrysden. When I click the "k-path selection" below tool menu, a window pop out, saying "the guessed bravais lattice type: not-supported (the XSF's group number is 1)". I tried a few structures, they all gave this message. Does this mean I can't get the special k-points from Xcrysden? Following is an input file I opened, could anyone help me to generate the special k-points? Thank you!</div>
