Extract directional wave spectra data (S-1 Wavemode)

Hello everybody !

I’m trying to extract the data used by the software to plot the directional wave spectra. I’m looking for some data in the form of Energy as a function of wavelength and azimuth, but for now I only found informations for the different partitions (dominant wavelength or each partition for example), so a lot of information is lost.
If anybody has an idea of where I can find such data in the .nc files, I would be very grateful !
