Well, 312 atoms with PBE0 is not really a small system.
I suggest to try the following:

  *   Drop EPS_FILTER_MATRIX or set the default value 0.0 for it
  *   Reduce EPS_PGF_ORB to something much less, e.g. 1.0E-20
  *   Restart from a wavefunction converged with PBE

I'm sorry. I thought that the input files contain an error.

The atomic coordinates are missing.

Hi
I get such errors in various calculations. For example, in calculations with hybrid and with meta-GGA functionals. At the same time optimizations of organic molecules with light elements do not give the error.

Hi

You have to provide a full input, preferentially as simple and small as possible, which gives that error.

Hi, everyone!
I am begginer at cp2k calculations. I am trying to optimize the geometries of coordination compounds with Cu, Cl, P, N, S and H atoms. During optimization, after the first SCF cycle, I get the CPASSERT error at build_overlap_matrix_low routine. Can anyone suggest what I'm doing wrong?
