Key Features of FFIND and Pancreatlas

Feature	Description	Purpose/Significance	Figures
Data Organization

Collections	datasets; the Collections page lists all available datasets, and each collection also has a dedicated page describing relevant background and details	provides digestible overview of data breadth; gives project-specific context	3A
Multiple viewing modes	• grid view (default): data displayed as thumbnails with minimal descriptors (for easy browsing) • temporal view: data grouped by curated age ranges (for data that is temporal in nature) • matrix view: data grouped by user-selected attributes (e.g., age and sex), displayed in a manner that easily identifies whether data exists for specific attribute combinations (e.g., 6 years and male, 4 years and female, etc.)	supports variable needs of user base; highlights key differences between data collections	2C and 3B
Data filtering	provides a flexible way to refine the data list into a subset of interest, allowing users to check boxes from lists of attribute options	familiar interface (typical of eCommerce); intuitive to end users	2C and 3B

Data Presentation

Thumbnails	image associated with each data object (in the case of Pancreatlas, an image) that highlights key features	provides visual identifier for each data object	3B and 4C
Preview mode	enlarges thumbnail and lists additional metadata (tissue, experimental attributes)	offers increased level of context while preserving filtered results	4D
Interactive browser (e.g., PathViewer)	in the case of Pancreatlas, a web-based (HTML5) client by OMERO Plus that supports channel interactivity (toggle on/off, change colors, change range), accommodates >30 channels within a single image, and offers multiresolution zoom (preprocessed pyramidal data)	allows users to view images in a web browser, from anywhere, without downloading any data; multiresolution zoom enables appreciation of cellular scale within whole-organ context	3C and 3D

General Browsing

Bookmarking	“save” buttons on data cards/previews let the user add data to a bookmarked collection that persists over multiple sessions	enables quick reference; users can build and share custom lists via unique URL	4D
Nomenclature page	lists all metadata terms, defining their biological relevance where applicable and providing diagrams to aid data interpretation	encourages field-wide adoption of metadata standards	4E
