Performance metric aggregation and display

performance-metric-aggregation-and-display

Summary

Aggregates multiple preprocessing workflow performance scores across five distinct evaluation criteria into a ranked summary and generates a circular barplot visualization of top-performing workflows. This skill enables comprehensive comparison and interpretation of preprocessing method performance for metabolomic data.

When to use

After running NOREVA's assessment functions (normulticlassqcall, normulticlassnoall, normulticlassisall, nortimecourseqcall, nortimecoursenoall) on preprocessing workflows, use this skill to synthesize performance results across all five criteria into a single ranked output and create a publication-ready circular barplot highlighting the top 100 workflows by overall performance score.

When NOT to use

• Input ranking file is not CSV format or lacks performance score columns required by norvisualization
• Assessment has not yet been run on any preprocessing workflows (no ranking file exists)
• You need detailed numeric performance values in tabular form rather than a visual summary

Inputs

• overall_ranking_CSV_file (from NOREVA assessment functions)
• cutoff_parameter (integer, e.g., 100)

Outputs

• circular_barplot_visualization (PNG or PDF format)
• NOREVA-Ranking-Top.100.workflows figure file

How to apply

Load the overall ranking CSV file containing aggregated performance scores from NOREVA's assessment output using R. Call the norvisualization function with the ranking file as input and set the cutoff parameter to 100 to filter for top-performing workflows. The function extracts workflow identities and their corresponding performance metrics, then generates a circular barplot where each workflow is positioned by rank and colored/sized by performance score. Save the resulting visualization as NOREVA-Ranking-Top.100.workflows in PNG or PDF format. The circular layout emphasizes relative ranking and facilitates visual identification of performance tiers across hundreds of preprocessing method combinations.

Examples

library(NOREVA); norvisualization(rankingFile='overall_ranking.csv', cutoff=100)

Evaluation signals

• Output figure exists and is readable in PNG or PDF format with filename matching NOREVA-Ranking-Top.100.workflows pattern
• Circular barplot displays exactly 100 workflows (or fewer if input ranking has <100 entries) ranked by performance score
• Workflows are arranged in circular layout with visible ranking order and performance metric scaling (bar height/color proportional to score)
• All 100 top-ranked workflows from the input CSV are represented in the visualization with no missing or duplicated entries
• Performance metrics span the expected range observed in the source ranking file (no compression, clipping, or transformation artifacts)

Limitations

• norvisualization requires the output CSV from one of NOREVA's five assessment functions; intermediate or manually-edited ranking files may cause parsing errors
• Circular layout becomes crowded and difficult to read if cutoff parameter exceeds ~150–200 workflows depending on label length and figure resolution
• The function assumes study assumptions (SAalpha, SAbeta, SAgamma) were correctly specified during upstream assessment; mismatched assumptions will yield misleading rankings
• Performance ranking integrates five criteria with equal weight by default; users requiring differential weighting of criteria must recompute rankings outside norvisualization
