<div align="left">Dear Users,<br><br>In order to visualise phonon modes
by xcrysden, I added the atomic displacement vector to the structure
specification section of the xsf file, as described in specification of
forces in xcrysden doc. But nothing has happened and the "Force setting"
icon is not active in "Modify' menu. <br>Any help would be so appreciated. <br><br></div>
