[gmx-users] GMX CPMD K+ ion problem

[Andrey V Golovin]

Dear all,
We successfully passed all examples in GMX-CPMD and some other stuff with
amberff with common atoms, but since we trying to deal with K+ (potassium)
in QM  part, we see every time absence of potassium in CPMD_inp.run, it's
just skipped. In very beginning CPMD shows right number of atoms in QM
group, but K is not mentioned in cpmd input file.

Potassium and pseudopotential was included in CPMD_inp.tmpl.
We checked different ways of including Potassium in ff, like amber_XX or
just K+.
Pseudopotential was build with Ultrasoft Pseudopotential Package.
Gmx-cpmd was compiled from site P. K. Biswas.

Any ideas?
Thanks in advance, Andrey
