Dear Paolo Sir,<br>Thank you very much.<br>Here i am still wondered if the actual volume is a^2*c for the bct, then sir why the pw.x code would half it's unit cell volume? Is it due to (just guess of mine is that here i am using 8 atoms super cell(2 atoms for Li, 2 atoms for In and 4 atoms for Te) but not sure.<br>
