    Use when when performing targeted peak detection on LC-MS data where compounds have been assigned expected ionization polarities (positive or negative mode) in the target list, and you want to prevent false peak assignments from the opposite polarity and avoid manual pre-filtering of raw data by.

    Pre Trained Model Fine Tuning · holobiomicslab

    Use when you have a small training dataset for molecular property prediction (e.g., <500 samples from PredRet or MoNA databases) and a pre-trained GNN model is available that was trained on a related, larger molecular corpus.

    Precursor And Noise Filtering · holobiomicslab

    Use when you have loaded raw tandem MS spectra (in MGF, mzML, or similar format) and need to prepare them for peptide identification, spectral library matching, or intensity-based analysis.

     Precursor M Z Based Filtering · holobiomicslab

     Use when you have an unknown MS/MS query spectrum with a known or measured precursor m/z value and need to search a spectral library (local or public: GNPS, MASSBANK, DrugBANK) to annotate the compound.
