Decks

Decks are collections of cards — captured viewport snapshots that preserve exactly what you see in the viewer, including camera position, channel settings, adjustments, and annotations. Think of them as a scientific presentation builder built into your analysis workflow.

​

What are decks for?

• Lab meetings — capture key findings as cards and present them directly from Relay
• Figures — build publication-ready figure collections with consistent styling
• Documentation — document your analysis workflow step by step
• Collaboration — share a deck with colleagues to show exactly what you found

​

Creating a card

1. Set up your view — zoom in on a region, adjust channels, add annotations
2. Click Add to Deck in the toolbar
3. The current viewport state is captured as a card, including:
   • Camera position (pan, zoom, rotation)
   • Channel settings (visibility, colors, LUTs)
   • Image adjustments (brightness, contrast, gamma)
   • Z-slice and time point
   • Annotation visibility settings
   • A thumbnail preview

Working with cards

​

Managing decks

You can create multiple decks to organize your work:

• Create — create a new empty deck with a title
• Rename — change a deck’s title
• Duplicate — copy an entire deck including all cards and annotations
• Delete — remove a deck and all its cards
• Reorder — rearrange decks in the sidebar
• Switch — click a deck to make it the active deck

​

Presentation mode

Enter Presentation Mode to display your cards full-screen:

• Cards display one at a time with their title and description
• Navigate between cards with arrow keys or buttons
• The viewer renders each card with its exact saved viewport state
• Present directly from your analysis environment — no export needed

​

Themes

Decks support built-in themes to style your presentation:

​

Card viewer sources

Cards can reference images from multiple sources:

• Files — local files loaded in the viewer
• URLs — remote images or Zarr datasets
• Scientific images — images from the scientific image store
• Cloud assets — files from Relay Drive (re-downloadable after refresh)

Each card stores enough information to reconstruct the exact view later, even after a page refresh.

​

Annotation integration

Cards support annotation filters that control which annotations are visible: Each card can have its own dedicated annotation document for card-specific markup.
