cellxgene-schema CLI must update validation in X (Matrix Layers)

[brianraymor]

Design

See X (Matrix Layers).

Assay	"raw" required?	"raw" location	"normalized" required?	"normalized" location
Visium Spatial Gene Expression	REQUIRED. Values MUST be de-duplicated molecule counts. All non-zero values MUST be positive integers stored as numpy.float32. If uns['spatial']['is_single'] is False then each cell MUST contain at least one non-zero value. If uns['spatial']['is_single'] is True then the unfiltered feature-barcode matrix (raw_feature_bc_matrix) MUST be used. See Space Ranger Feature-Barcode Matrices. This matrix MUST contain 4992 rows. If the obs['in_tissue'] value is 1, then the cell MUST contain at least one non-zero value. If any obs['in_tissue'] values are 0, then at least one cell corresponding to a obs['in_tissue'] with a value of 0 MUST contain a non-zero value.	AnnData.raw.X unless no "normalized" is provided, then AnnData.X	STRONGLY RECOMMENDED	AnnData.X
