Overview

Norm-ISWSVR normalizes metabolomics tables by combining internal-standard correction with support-vector-regression-based adjustment. Its Python implementation supports matched or unmatched internal-standard settings, cross-validation and hyperparameter search.

Scope and considerations

Designed for

  • Norm-ISWSVR normalizes metabolomics tables by combining internal-standard correction with support-vector-regression-based adjustment.

Not designed for

  • Correcting every biological/technical confounding pattern or establishing accurate absolute concentrations solely by normalization.

Important requirements

  • Documented Python dependencies, abundance and sample CSV tables, internal-standard information and appropriate QC/run metadata for the selected mode.

Considerations

  • Review matched-standard assignments, QC coverage and biological preservation. Injection-order and batch columns are optional in the template but their absence limits corresponding diagnostics and interpretation.
