Hi all vasp users, I would like to know about the how the conversion from cartesian coordinates (in POSCAR) to direct coordinates (in CONTCAR) happens in vasp calculation. I have found few threads in this forum regarding this issue. But those are not satisfactory. I want to know the exact procedure of this conversion. We know that the direct to cartesian coordinates conversion should be like:

cartX = directX*Scale factor*A_X+directX*Scale factor*B_X+directX*Scale factor*C_X
etc.
But we also know that when we tried to do so from CONTCAR we did not get the converted cartesian value that we should get. So I am requesting you if any one can give me this knowledge It will be very helpful for me as well as for those who will search for it like me. Thanks in advance.
