Raman analysis processes spectroscopy files, reads acquisition settings from filenames, and corrects each spectrum before detecting peaks. Spectra are stored on a common Raman shift axis so that results from different files can be compared directly.

​
Overview

The Raman pipeline processes data in three stages:
  1. File parsing: reads the spectral axis and intensity from uploaded .txt or .csv spectroscopy files
  2. Metadata extraction: reads laser power, exposure time, accumulation count, and excitation wavelength from the filename, along with descriptive details such as sample identity and measurement location
  3. Spectrum processing: removes cosmic-ray spikes, normalizes intensity by laser power and exposure (when known), calibrates the shift axis against silicon (when a silicon peak is present), subtracts the background, and detects peaks

​
Adding Data

Upload .txt or .csv spectroscopy files through the data page. Each file should contain a Raman shift column and an intensity column. Processing starts automatically once the upload completes.To enable intensity normalization, include the laser power and exposure time in the filename, for example SampleA_center_532nm_2mW_30s_10ac.txt. See Photoluminescence for the full filename convention.

​
Viewing Results

Once processing completes, the workspace displays an interactive spectrum chart.Region filter: Use the Regions dropdown above the chart to show or hide detected peaks. Each Detected Peak is shown as a shaded band on the chart.Series filter: Use the Series dropdown to show or hide the intensity trace.A configuration drawer is accessible via the gear icon, though no configuration options are available yet.
