        Progress

        • the first complete draft of internal note including interpretations of observed non-closure;
        • submitted CLHCP 2026 poster application;
        • re-implemented T&P core function in my code:
          1. T&P-specific collection construction, merging and ordering
          2. Self-exclusion and tag multiplicity
          3. Highest-accepted-mass tag choice and multiple-probe handling
          4. Pair-role associations

         

        To-Do List

        • update results using new electron derivation (ungoing);
        • git repo for my analysis framework;
        • Wed discussion with Dominik to collect note comments;

        TODO:

        • Rerun onyx with full dataset
        • Rerun test with odd data
        • Start training ttH focused SPANet
