GC-MS mVOC heatmaps
Compare every reported GC-MS target across biological and reference profiles in a dataset-specific, pheatmap-style matrix.
GCMS-ZIMMER-2026-03 · Clinical comparison
Zimmer blood-bottle and PS-Ortho GC-MS
114 mVOCs / reported targets × 13 profiles
mVOC abundance by bug or sample
Within-feature z-score · dimensionless. Rows are mVOCs / reported targets; columns are individual bacterial or sample profiles.
Blank, media-control, matrix-control, system-blank, and pooled-QC profiles are excluded.
5 panel targets excluded by the analysis preprocessing contract.
Hover or click a cell to inspect it. Focus the heatmap and use the arrow keys to move between mVOC–profile pairs.
Methods, provenance, and interpretation
Analysis-compatible within-target z-score of the half-minimum-imputed log2(area + 1) matrix, fitted across primary-analysis profiles with population standard deviation (ddof=0). Fitted on 77 primary-analysis profiles; observed zeroes remain zero and imputed cells are identified in the inspector and download.
Zimmer full 119-target export · All targets in the current reviewed quantitative export; inclusion is not evidence of biological relevance or confirmed chemical identity.
Only biological and reference profiles are displayed. Blank and control profiles remain in the evidence database but are excluded from the heatmap, its filters, API response, and CSV download.
Screening evidence. Compound names are reported targets, not confirmed-standard identities. Reported or library-matched names are not equivalent to confirmation with an analytical standard.
