DIFFATONCE / VIDEO GUIDES

From the first spectrum to the report, step by step.

Six guided workflows in DiffAtOnce Prime and ResinAtOnce: spectrum, map, local signal, Beatrix, corrections and report. Play at your own pace, with Spanish and English captions and transcripts.

WPF · WINDOWS · ES / EN

One task per video.

Guided sequences of actual WPF-window captures, not continuous mouse recordings. Actual Spanish or English narration matching the page language, generated locally with a synthetic voice; ES/EN captions and transcripts synchronized to each version. Select CC, pause to follow the steps or download the text. They can be followed without sound, and no external-model calls occur during playback.

DiffAtOnce Prime / USE CASES

Explore, calculate and review.

From the full map to a single-signal attenuation, with contextual help and visible limits.

Prime · from project to DOSY map

Review a saved map, its parameters and lateral-projection bands without changing the result.

Audio: English · locally generated synthetic voice

  1. 00:001 · Identify the context
  2. 00:262 · Inspect the parameters
  3. 00:503 · Explore a band
  4. 01:124 · Restore the view and export
Steps, provenance and transcript
  1. 1 · Identify the context
  2. 2 · Inspect the parameters
  3. 3 · Explore a band
  4. 4 · Restore the view and export

Evidence: Replay of a saved experimental project. No new acquisition or physical experimental validation is performed. Originals preserved. This workflow demonstration is not experimental validation and does not confirm species or absolute molecular masses.

Creation: guided WPF-window capture sequence. Local speech engine: Windows System.Speech / Microsoft Zira Desktop.

Workflow guidance, not a scientific guarantee.

Curves and warnings come from application windows. Captions and framing guide usage; they do not add components, hide residuals or change calibrations. Numerical convergence, noise compatibility, identifiability and experimental validation are separate checks. Unknown values remain unknown.

Media is served locally from diffatonce.com: no YouTube, Vimeo or external-player cookies. Optional site analytics retain their separate preferences; declining them does not block videos.

DIFFATONCE LEGACY · WEB / WPF
