Overview
The PL pipeline processes data in three stages:- File parsing: reads energy and intensity columns from uploaded CSV spectroscopy files
- Metadata extraction: an LLM parses the filename to recover sample identity, measurement location, laser power, exposure time, accumulation count, and energy range
- Intensity normalization: divides raw intensity by the product of power, exposure, and accumulation so that spectra taken under different conditions can be compared on equal footing
Key Metrics
| Metric | What It Tells You |
|---|---|
| Energy | Spectral position of emission features, in the units recorded by the instrument (typically eV or nm). |
| Intensity | Emission strength. When metadata is complete, intensity is normalized by acquisition parameters. When metadata is incomplete, raw counts are preserved. |

Adding Data
Upload CSV spectroscopy files through the data page. Each file should contain two columns: energy and intensity. Processing starts automatically once the upload completes.The pipeline extracts metadata (sample ID, measurement location, laser power, exposure, accumulation) from the filename. Including these details in the filename enables automatic intensity normalization.Viewing Results
Once processing completes, the workspace displays a spectrum chart plotting energy vs. intensity. A status badge indicates pipeline progress.If the filename does not contain enough metadata to determine power, exposure, and accumulation values, the spectrum displays raw (unnormalized) intensity. The normalization flag in the results indicates whether normalization was applied.
