<p>Dear Manzoor,</p>
<p>a very simple way is to use ASE (a python package). If you have
it installed (e.g. "pip install ase" or if you use conda "conda
install -c conda-forge ase") just run the following two lines in
python:</p>
<p>from ase import io</p>
<p>io.read('CONTCAR').write('C2NTa2.xyz')</p>
<p>This will convert the CONTCAR to C2NTa2.xyz. The second line of
c2n.xyz contains Lattice="xx xy xz yx yy yz zx zy zz" which are
the 9 numbers that define the lattice. You can use these to set A
xx xy xz B yx yy yz and C zx zy zz in the &CELL section of the
input file. If you explicitly set A, B,and C then ANGLE is not
needed anymore.<br>
</p>
<p>Cheers,</p>
<p>Fabian<br>

<div>I don't think there is a problem with the structure of
C2N monolayer. Its structure is well documented in
literature. However, I feel I may be making some mistake
in terms of the format of the xyz file and cell parameters
in the input file. If you know how generate the xyz
coordinates for VASP CONTCAR in the CP2K format, that
might help me troubleshoot this problem.</div>
