Automatic curve extraction

Upload the spectrum image and review the automatic overlay. If it is correct, download the CSV or use the spectrum in the workstation. If one section is wrong or missing, adjust it manually or stay on this page and roughly draw over the correct curve.

Mark the correct curve

Draw over one section that the system missed or followed incorrectly. A rough stroke is enough — you do not need to trace the curve accurately.

Keep the stroke near the correct visible curve. The system uses it to understand the right region and how far the automatic trace drifted, then re-extracts from the original image.

Draw mode is active by default. Switch to Move image, drag the canvas, use the arrow buttons, or use the mouse wheel to inspect a local section; switch back before drawing.

Press and drag along the correct curve. One continuous stroke is enough.
