rescore-column-standardization
Summary
Rename and standardize Rescore (k) output columns from FIDDLE v2.0.0's Siamese-architecture rescore model to a uniform format for downstream analysis and CSV export. This ensures consistent column naming across different inference runs and integrations with external tools.
When to use
After running FIDDLE v2.0.0 inference on MS/MS spectra and obtaining ranked formula candidates with confidence scores, apply this skill when the rescore model outputs columns named Rescore (0), Rescore (1), ..., Rescore (k) and you need to export results to CSV with standardized, machine-readable column headers for integration with other analysis pipelines or comparative studies.
When NOT to use
- Rescore columns are already standardized or in a non-parenthetical naming format — standardization is unnecessary.
- Output is intended for direct ingestion by a tool that explicitly expects the original parenthetical format (Rescore (k)) — check tool documentation first.
- Inference has not yet been run or rescore model was not included in the FIDDLE pipeline — no columns to rename.
Inputs
- DataFrame or table with raw FIDDLE v2.0.0 rescore model outputs (Rescore (0), Rescore (1), ..., Rescore (k) columns)
- Top-k ranking parameter (typically 5 for default output)
- Output file path for CSV export
Outputs
- CSV file with standardized Rescore column names
- Renamed DataFrame ready for downstream analysis or tool integration
How to apply
After executing the Siamese-architecture rescore model inference via FIDDLE (v2.0.0), extract the raw Rescore (k) output columns where k ranges from 0 to the top-k ranking (typically 0–4 for top-5 candidates). Identify the pattern of numeric suffixes in the column names and apply a consistent renaming rule (e.g., map Rescore (0) → Rescore_0, Rescore (1) → Rescore_1, etc., or adopt a domain convention such as Rescore_rank_0, depending on downstream tool compatibility). Validate that all k columns are present and contain numeric confidence scores in the expected range (typically [0, 1] for neural model outputs). Finally, export the dataframe to CSV ensuring the renamed columns are written with the standardized header row.

Evaluation signals
- All Rescore (k) columns are successfully renamed to the standardized format with no missing or duplicate column names.
- Rescore values remain unchanged (numeric, in valid range [0, 1] or expected score range) after renaming.
- CSV header row contains exactly top-k renamed Rescore columns (e.g., Rescore_0 through Rescore_4 for top-5 output).
- Row counts and column order are preserved; no data is dropped or reordered during the renaming operation.
- Downstream tools or comparative workflows accept the renamed CSV without parsing errors or schema mismatches.
Limitations
- Renaming is a surface-level operation and does not validate or correct underlying score semantics or calibration; scores remain as output by the neural model.
- If the rescore model was not included in the FIDDLE inference pipeline (e.g., TCN-only prediction), no Rescore columns will be present and standardization cannot be applied.
- Different versions or forks of FIDDLE may use variant column naming patterns (e.g., Rescore_k, Rescore[k], Rescore-k); consult the specific tool version documentation to determine the exact input pattern.
- Standardization logic must be adapted if the number of top-k candidates changes or if the output format differs from the documented Rescore (k) template.
