<pre>Dear users <br>I could not understand how one can set atomic positions in any calculations.<br>In perticular if I know the space group PNMA62 and fractional coordinate of <br>sample LaMnO3 <br>molecule (Everywhere position of La Mn O1 O2 are given How will I find out atomic position of
<br>3rd Oxygen using symetry??? Any reference for example??? ). Is anybody aware of how coordinates in premittive cell can be <br>generated for perticular space group and frictional coordinates. How will I make a supercell of 4 formula unit for Orthorhombic structure????
<br>Is there any good reference on formation of supercell for non cubic crystal?????<br>Why the manual is not as clear as ABINIT in PWSCF???? <br>Thanks in <br>anticipations. <br>With best regards<br>Amit<br></pre>
