Sample Data¶

VIPP 0.12.0a3 ships 13 deterministic microscopy-style samples that are available inside Image Source:

Image Source > Source = sample

This is the normal route when building or adapting a workflow. The sample menu then lists every bundled sample without adding raw layers to napari first.

Napari's sample-data menu is still useful when you want to inspect raw sample layers directly:

File > Open Sample > VIPP synthetic microscopy samples

Bundled Samples¶

Sample	Axes	Purpose
`VIPP synthetic volume`	`ZYX`	Basic grayscale z-stack with sphere/tube-like structures.
`VIPP synthetic multichannel volume`	`CZYX`	Three-channel fluorescence-like volume with blue/DAPI-like nuclei, green/FITC-like neurites, and red/TRITC-like puncta for channel splitting and segmentation.
`VIPP synthetic time-lapse multichannel`	`TCZYX`	Preferred starter sample with time, channel, z, y, and x axes.
`VIPP synthetic measurement summary`	`TYX`	Known object counts/areas per timepoint for summary validation.
`VIPP synthetic object morphology`	`YX`	Circle, ellipse, rectangle, and concave 2D objects for derived morphology.
`VIPP synthetic 3D mesh morphology`	`ZYX`	Anisotropic 3D objects for mesh volume, surface, convex hull, and sphericity checks.
`VIPP synthetic skeleton network`	`ZYX`	Sparse 3D skeleton-style network with known endpoints, junctions, spur, fragment, and isolated voxel.
`VIPP synthetic advanced skeleton network`	`TZYX`	Multi-timepoint skeleton stress test with loops, fragments, graph tables, and anisotropic scale.
`VIPP synthetic colocalization`	`CZYX`	Two-channel partial-overlap structures for colocalization, RACC-like output, and object association.
`VIPP synthetic deconvolution image`	`YX`	2D blurred/noisy image for PSF-aware restoration review.
`VIPP synthetic measured PSF`	`YX`	2D measured-PSF-like kernel for PSF preparation.
`VIPP synthetic 3D deconvolution volume`	`ZYX`	3D blurred/noisy volume for volumetric restoration review.
`VIPP synthetic 3D measured PSF`	`ZYX`	3D measured-PSF-like kernel for volumetric deconvolution.

Documentation Samples Versus Core Samples¶

Core samples should stay small, deterministic, testable, and broadly useful.

Documentation-only samples can be more tutorial-specific. A documentation sample can become a core sample when it supports a stable workflow and has test coverage.

Synthetic truth is valuable for demonstrations and regression checks, but it does not establish performance on a biological assay. Validate a transferred workflow on representative real data and independent references.
