Calculate diffusion and generate a report DiffAtOnce Legacy · desktop 00:00 — Review the fit conditions Some published desktop labels remain in Spanish; this English narration guides the controls. We open Diffusion for the active series. The screenshot shows the example's sequence, gradient shape and timings. Always check these parameters and the calibrated gradient before interpreting the slope as diffusion. 00:21 — Retain each point selection Point selection is reversible. Point fifteen has been excluded and is visually distinguished here. Preserve the original observation and document the reason for each exclusion, rather than seeking only an attractive fit. 00:36 — From the fit to D and Rh The point is then restored and the diffusion coefficient calculated. The mathematical example also produces a hydrodynamic radius and R². These synthetic results are not experimental uncertainty estimates or calibration validation. 00:53 — Compare equivalent geometries Shape and size compares a sphere, cylinder and ellipsoid. The prolate ellipsoid uses an explicitly chosen axis ratio. That geometry is a model hypothesis, not a confirmed molecular identity. 01:08 — Preserve methods and provenance The application has saved a real PDF report of the demonstration. The dialog confirms the generated output. Before sharing it, review parameters, selections, sources and the limitations of the model estimates. 01:25 — Keep the result with its peak Back in the spectrum, the signal panel brings together its values and applied models. Check which resonance and ramp you are reading. Keep the project with the report to preserve data and decisions. Synthetic data demonstration. This is not experimental validation or a confirmed molecular identification.
