Alignment

Interpolation uses the first listed file’s X grid inside the common measured overlap. Never extrapolates.

Normalize each curve to its first Y = 100%

Band = ±1 sample SD across curves; not a confidence interval.

Per-file checks

Within-file Y summaries are not independent replicate statistics.

Check comparability before combining. Use consistent units, matching experimental conditions, and genuinely independent replicates when interpreting SEM. Missing selected values and duplicate X values stop the analysis rather than being silently removed. Read the complete method →
