1. 1 · FAQFrequently asked questionsShort answers to the questions people ask most about Athanor, each with a link to the guide that goes further.
2. 2 · How-toWhy an atom is flaggedThe badge at the bottom left of the canvas counts problems in what you drew, such as a carbon with five bonds (an error) or a stereocenter with no wedge (a warning). Click it to see the list. Athanor flags problems and never changes your structure on its own.
3. 3 · How-toA file will not openAthanor says why a file did not open, in the notice. Check the extension matches the format, try saving it from the other program as CDXML or MOL V3000, and if it still fails, report it with the file.
4. 4 · How-toAn export looks wrongIn Export, raise Resolution for a sharper PNG, set Background to White if a transparent picture looks wrong, pick the journal Style, and switch between Selection and Whole page if parts are cropped or missing. For print, use PDF or SVG, which stay sharp at any size.
5. 5 · How-toA plugin stopped workingAthanor runs every plugin in a sealed sandbox, so a plugin that fails cannot harm your document. The notice names the plugin and what went wrong. A plugin that fails three times in ten minutes is turned off for the session; press Turn back on in the notice, or reload Athanor.
6. 6 · How-toDesktop app updatesThe Windows app checks for a new version a minute after it starts and every 30 minutes after that, downloads it in the background, and shows a Restart to update button. Your work is saved before it restarts. After seven days the update becomes required. Microsoft Store installs are updated by the Store.
7. 7 · How-to · AccountStorage is fullWhen your account is full, nothing is lost. New changes stay on this device and stop syncing until you free space or move to a plan with more. Empty the trash or delete documents you no longer need, then keep working and sync resumes on the next save.
