Thanks for clarifying the expected behavior. I'd change the `Post-process spectra - step 2` (cell 10) [here](https://github.com/iomega/spec2vec_gnps_data_analysis/blob/master/notebooks/iomega-5-train-spec2vec-model.ipynb) to something like the following: ``` def post_process_step2(s): s = reduce_to_number_of_peaks(s, n_required=10, ratio_desired=0.5)...

The above code block still gives the same error. `Cannot use ratio_desired for spectrum without parent_mass.` I'm not sure if `require_precursor_mz(s)` is behaving as expected. (I don't think I have...
