    Use when you have a large collection of MS/MS spectra (hundreds of thousands to millions) that need to be clustered, you have already constructed nearest neighbor indexes on low-dimensional spectrum vectors (via feature hashing), and you need to compute only the relevant pairwise distances between.

    Spectral Entropy Quality Assessment · holobiomicslab
    Use when after feature detection and alignment in untargeted MS data processing, when you need to filter or rank candidate metabolite annotations by spectral quality before committing to xenobiotic metabolite assignments. Use when combining fragmentation similarity scores (e.

    Spectral Feature Vector Aggregation · holobiomicslab
    Use when you have generated per-sample MS2 fingerprints (as spec2vec document representations counting MS2 peaks and neutral losses to precursor in each sample) and need to align them into a single matrix for downstream cross-sample comparison, filtering, or visualization (e.

    Spectral Library Record Structuring · holobiomicslab
    Use when you have extracted MS1 and MS2 scans (in mzML/mzXML format) from raw chromatogram files and possess user-provided metadata (retention time, m/z, compound name, molecular weight, annotation fields) that you need to bind together into a queryable spectral library record for local compound.

    Spectral Match Result Consolidation · holobiomicslab
    Use when you have executed batch searches of MS/MS spectra against multiple domain-specific MASST indices and need to integrate the resulting match outputs into a single coherent view.
