Human liver¶
Cohort human-liver, catalog release 2026-11-01.
This primer describes a cohort; it is not a benchmark. It does not rank papers, technologies or methods. The batch correction (Harmony on the section) is shown for orientation only: well-mixed embeddings are not proof of a correct biology. This cohort's technologies may also differ by paper and lab. Where one paper used one technology, a technology effect can't be separated from a paper effect.
The analysis below runs the primers package at a fixed reference. To install the same code:
pip install "sddb-primers @ git+https://github.com/theislab/spatialdata-db-client@4d7af340849c00077f9d21c5b54af9e689a4a070#subdirectory=primers"

The batch variable is the paper. A member's paper is its DOI. Without a DOI it is its GEO series, else its first collection, else its study id. A DOI that one member of a series or collection carries is given to the other members of that group. All 10x Genomics demo datasets count as one paper, because they come from one company and not from independent labs. Harmony runs on the section (dataset_uid), not on the paper. 10x often publishes one section in several Space Ranger releases, and only the newest release is kept, and the others are dropped as re-releases. Serial sections of one 10x block count as one section in the mixing statistics.

Embedding¶
Each technology family is embedded on the genes every member measured. A joint view across families is added only when the gates pass. The parameters of the embedding come first.

entropy: How evenly the batch labels are spread among each observation's 30 nearest neighbours, divided by log(min(30, number of labels)): 0 when all neighbours share one label, 1 when the labels are as evenly spread as the neighbours allow. other_share: The share of each observation's 30 nearest neighbours that carry another batch. Well mixed is not the same as biologically right: a correction can also mix cells that differ for a real reason, such as tissue or disease.

Draft reading, to be reviewed by the Lead¶
Each statement below is generated from the reading table of its view and cites the numbers in it. The score of a compartment is the mean, over a cluster's observations, of the mean log-normalised expression of the compartment's marker and fallback genes. Compartments can sit inside others (goblet cells are epithelial), so the top compartment of a cluster does not exclude the runner-up.
