I am looking at some issues with propagation accuracy and this is useful to have. The same can be achieved by using PA-CMD and manually putting in omega_n as the target frequency, but this is more convenient.

I would like to to move the printing of the "normal mode report" somewhere nicer so that it is not printed twice - accepting suggestions.

One problem that I notice is that in test runs with 32 beads (but not with 8 or 16), LAMMPS clients crash with ERROR: Out of range atoms - cannot compute PPPM (../pppm_tip4p.cpp:107). This also happens in the master and with <normal_modes mode="pa-cmd">[0.0301987497472]</normal_modes>. I will show a test case if I can't figure it out.

As the dynamics runs at nT, the potential should also be scaled down
by n to achieve the same effect as in PIMD with temperature T and
target frequency omega_P.

@ceriottm, are you interested in having this option for easy comparison to other programs, or shall we drop it? I have no strong preference either way.

Yes, something like that, with no frequency specified.

I still think that Sphinx is the best solution for documentation, both written and automatically generated (input file and the code itself). I can spend some time on it in the summer and I think we really should have it for 2.0.

Hey @OndrejMarsalek should we resurrect this, test, wrap up and merge or is this functionality outdated?
