Quick start
Choose a workspace
Use Analyze for spectrum or map inspection. Use Fitting when you need numerical peak decomposition for one spectrum.

How to use RamanQuick
Upload Raman data, inspect spectra, fit components, and export editable results.
Supported files
Supported formats
CSVTXTDATASCXYWDF
Text-based files should include Raman shift and intensity columns. WDF files are supported for single-spectrum fitting workflows.
Analyze
Analyze workspace
Analyze is best for quick inspection, visual comparison, map-oriented workflows, and editable outputs.
1
Upload spectrum or map data
Load Raman spectral data for quick inspection, visualization, and material-oriented analysis.
2
Inspect key Raman features
Review peak positions, intensity trends, and processed spectra before interpreting the result.
3
Apply basic preprocessing
Use baseline correction and spike removal only when needed. Keep the raw spectrum available for comparison.
4
Export editable outputs
Save analysis-ready data and figures for reports, presentations, and manuscript preparation.
Fitting
Fitting workspace
Fitting is designed for single-spectrum peak decomposition. It helps compare center position, FWHM, amplitude, area percentage, residuals, and fit quality.
1
Upload one Raman spectrum
Fitting is designed for single-spectrum peak decomposition and numerical comparison.
2
Choose fitting range
The fitting range is automatically initialized from the uploaded spectrum and can be adjusted manually.
3
Prepare the signal
Optional spike removal and baseline correction are applied before fitting.
4
Set components
Component 1 is initialized near the strongest detected peak. Additional components can be added manually.
5
Check fit quality
Review the total fit, component curves, residual, R², RMSE, and warning messages.
6
Export workbook
Download an Excel-compatible workbook containing parameters, curves, processing log, and numerical fit results.
Baseline Correction
Use baseline correction when the spectrum has a slowly varying background. Start with Simple Baseline and compare the original and corrected signals before interpretation.
Spike Removal
Use spike removal for narrow cosmic-ray-like artifacts. Avoid Strong mode unless the artifact is clear, because sharp Raman features can also be affected.
Processed signal
In Fitting, the processed signal is the spectrum after optional spike removal and baseline correction. This signal is used for fitting and export.
Export
Export workbook
Fitting export creates an Excel-compatible workbook for later analysis, plotting, and manuscript preparation.
Parameters
Component name, initial center, fitted center, shift, FWHM, amplitude, area percentage, and model.
Curves
Raman shift, processed signal, total fit, component curves, and residual values in the selected range.
Processing Log
File name, fitting range, baseline mode, spike removal mode, selected points, and component count.
Numerical Fit
R², RMSE, residual maximum, fit quality, and overfitting risk.
Sample data

Troubleshooting
Common issues and fixes
Use this checklist when upload, graph display, fitting, or export results look unexpected.
The file does not load
Check whether the file contains numeric Raman shift and intensity columns. For WDF files, RamanQuick currently uses the first spectrum for single-spectrum fitting.
The graph looks flat or empty
Confirm that the Raman shift range and intensity columns were parsed correctly. Also check whether the selected fitting range contains data points.
The fitted peak center looks wrong
Adjust the component center manually or narrow the fitting range around the expected Raman feature.
Baseline correction changes the spectrum too strongly
Use Simple Baseline first. If the result still looks unreasonable, compare Original, Corrected, and Both views before fitting.
The residual looks structured
A structured residual usually means the model, fitting range, baseline, or number of components should be reconsidered.
Export values look different from expectation
Check whether the exported workbook uses the selected fitting range and processed signal rather than the full raw spectrum.
Interpretation note
RamanQuick helps organize Raman analysis and fitting workflows, but numerical fitting alone does not prove material assignment. Always check the raw data, preprocessing choices, residual structure, peak width, instrument conditions, and physical plausibility before drawing conclusions.
