@ntolley Dylan mentioned his recollection that we discussed this being part of the v0.5 release (estimated late Spring 2025) instead of the v0.4 release ("soon", in the beginning of 2025). Should this issue be changed to target v0.5?

Question @ntolley @dylansdaniels : will this allow spectrogram-plotting of our shorter, default ERP simulation in the GUI? I ask because currently, y'all agreed that the spectrogram NOT plotting for the default GUI simulation is expected behavior (see #937 (comment) ). However, in our ERP tutorial (here https://jonescompneurolab.github.io/hnn-tutorials/coregui_erp/coregui_erp.html ), which uses the default GUI simulation settings, there is a specific section "4.3 Viewing ERP Spectrograms" about these spectrograms. Currently, these plots will not be generated for reasons in the first link. Whatever changes Nick derives to our spectral analysis, I think we should probably ensure it works in the shorter ERP case as well.

Good catch! I think we can safely remove that section from the tutorial. It's really just there to show off the GUI functionality, but it's not important or relevant for that tutorial.
