Dear Mr. Samaneh Javan,<br><br>Thank you very much for your help. I have the xcrysden software installed in my system. But, I could not select <gamma K M sigma gamma delta A S H L R A> direction and at the same time <L U M> direction in that software. It only allows me to select the high symmetric points - like gamma, sigma, M, H etc. I will be very glad if you can give me the step by step instruction to do it.<br>
<br>Thank you again.<br><br>Debojyoti Mukherjee <br><br> <br>
