Dear QE users,<br>I am interested in plotting phonon dispersion curve of a crystal having space group Cmcm (63) [orthorhombic base centred structure with b>c>a]. For that I took some of the special k-points from the website : <a href="http://www.cryst.ehu.es/cgi-bin/cryst/programs/nph-kv-list">http://www.cryst.ehu.es/cgi-bin/cryst/programs/nph-kv-list</a> (for b>a). I want to see phonon branches from 'Gamma' to 'Y' through point 'C' (special k-points as mentioned in that site). 'C' point is given as u-1/2,u+1/2,0 ex.<br>
My question is how to write this special k-point path in <a href="http://matdyn.in">matdyn.in</a> file.<br><br>Thanks in advance<br>P. S. Ghosh<br>BARC,INDIA<br>
