Version 0.9.0

• More stable identification counts
  • Improved the FDR and candidate-ranking workflow to make identification counts more consistent across runs.
  • Search groups and precursor classes are handled more consistently during FDR estimation, reducing avoidable variation in reported IDs when the same dataset and configuration are analyzed repeatedly.
• Refined glycoproteomics scoring features
  • Added more glyco-specific scoring features for N-glycopeptide candidates.
  • The glyco workflow now captures diagnostic-ion coverage, Y-stub coverage, total library fragment coverage, all-fragment intensity and height correlations, oxonium-ion intensity fraction, Y-stub intensity fraction, and Y-stub-to-backbone intensity ratio.
  • These features give the FDR model more direct evidence about glycan-related signal, improving the distinction between plausible glycopeptide matches and weaker candidates.
• Improved glycoproteomics extraction workflow
  • Refined N-glyco fragment extraction so backbone, oxonium, and Y-stub evidence can be evaluated together instead of relying only on shared peptide-style fragment evidence.
  • Added more focused handling of observed glyco fragments and signal fractions, improving the feature set available for glycoproteomics review and scoring.
• Expanded modification coverage
  • Added Dimethyl modification chemistry support in the modification metadata used by the prediction and fingerprint workflows.
  • This improves compatibility for workflows that include dimethyl labeling or related modification-aware library generation.

• GUI required settings warning
  • Fixed a bug where the warning dialog did not appear when required GUI settings were missing.
• Protein name output
  • Fixed an issue where incorrect protein names were reported in the output.

Version 0.8.0

• Glycoproteomics support
  • Added N-glycopeptide library generation and search support for glycoproteomics workflows.
  • SynapSpec can generate glycopeptide candidates from N-glycosylation motifs, combine peptide backbone information with glycan compositions, and use glyco-aware fragments such as diagnostic ions and Y-stub ions during candidate generation and scoring.
  • Glyco search is integrated into the broader DIA workflow, including GUI settings, spectral library generation, prediction, extraction, and result handling.
• Feedback-driven N-glyco expansion
  • Added a bounded, tier-based glyco expansion strategy to avoid generating an unmanageable glycopeptide search space all at once.
  • Regular peptide evidence can unlock protein-level glyco candidates, and glyco hits can progressively unlock additional glycan tiers up to the configured limit.
  • This makes glycoproteomics search more practical for large FASTA inputs while keeping the workflow controlled and interpretable.
• Unspecific search support
  • Added support for unspecific search mode, where peptides are not required to follow enzyme cleavage rules at either terminus.
  • Supported search modes now include specific, semi-specific, N-terminal specific, C-terminal specific, and unspecific candidate generation.
  • This broadens SynapSpec's use cases for workflows where cleavage specificity is uncertain or where users want to explore noncanonical peptide evidence.
• Dynamic and simple search strategies
  • Added two search strategies for broad candidate generation.
  • Dynamic mode uses search feedback to expand the candidate space progressively, reducing memory pressure for semi-specific, unspecific, and glyco searches.
  • Simple mode generates candidates upfront for users who prefer a straightforward, predictable search plan.
• Improved prediction models and feature generation
  • Updated RT, MS2, charge, and coelution-related model support, including instrument-aware prediction assets and fingerprint caching.
  • Improved modified-sequence handling and model inputs so modified peptides and glycopeptides can be represented more consistently across library generation and prediction.
  • These updates support higher identification counts and better downstream scoring behavior in the expanded search modes.
• Expanded external library support
  • Added support for MaxQuant msms.txt as an external library source.
  • This makes it easier to reuse existing search outputs and combine external evidence with SynapSpec's in-silico and hybrid library generation workflows.
• Decoy strategy improvements
  • Added a unified decoy strategy framework with support for RT-shift, shuffle, glyco-aware, and unified decoy generation approaches.
  • This provides a more flexible foundation for FDR estimation across regular, broad-search, and glycoproteomics workflows.
