I have a new parser for OpenMX DFT code http://www.openmx-square.org/, living at GitHub - ondracka/nomad-parser-openmx and similarly to the LOBSTER parser I would like it to be included into upstream nomad (we have some publications nearing completions for which we would like to dump some OpenMX data to upstream archive).
The current status is that basic parsing of scf and MD stuff works: system, forces, velocities, method, sampling_method, eigenvalues, etc. Some examples of missing items are DOS and bandstructure parsing. All supported stuff should be quite thoroughly tested, however the code quality and especially cleanliness is likely not too good. Longterm I would like for the parser to be incorporated to the NOMAD CoE and Laboratory repo at github and I’d be willing to do some further cleanups if requested.
