A Simple Traceability Checklist for Materials Research Data

Keep a defensible path from sample label and instrument export to processed figure and written conclusion.

Treat the sample label as a key

A sample name should connect preparation, treatment, measurement, and analysis. Use a stable identifier rather than relying on a folder name remembered by one person. Record synthesis batch, relevant conditions, and any deviation from the plan. The label becomes the anchor for every later file.

Archive raw exports before editing

Keep instrument exports unchanged and copy them into a working area before transformation. Record the instrument, collection date, method, and operator notes. A figure can be recreated only when the original signal and its acquisition context survive.

Write down every transformation

Background correction, smoothing, normalization, fitting ranges, and excluded points should be visible. A small text file, notebook, or script can preserve these decisions. The purpose is not bureaucracy; it is the ability to revisit an interpretation when a collaborator asks a better question.

Separate observation from explanation

Write what the trace shows before writing why it may have happened. This prevents a preferred mechanism from shaping the description of the data. In a lab notebook or analysis note, keep observations, transformations, and interpretation as separate headings.

Package the result for review

A reviewable result includes the raw file, processed data, parameters, figure, and a short note describing the conclusion and uncertainty. This package makes internal review easier and supports a cleaner transition from exploratory analysis to a report or manuscript.
