Landscape of histone modifications in a sponge reveals the origin of animal cis-regulatory complexity
We deep sequence DNA associated with immunoprecipitated chromatin containing histones with specific post-translational modifications (PTMs) to identify transcriptionally active or repressed regions of the genome of the sponge Amphimedon queenslandica.
Provenance — who produced it, who reused it
Linked to 2 papers in the literature. Roles are inferred factual signals (who deposited the data vs who reused it), with counts — never a judgement about any author.
Deep data QC
insufficient data to scoreStandardized, field-standard QC computed by touching the data — every metric states how it was obtained
The insufficient grade is a transparent weighted average. Each metric below scored from 0–100% against the published ChIP-seq thresholds, weighted by its importance; nothing is hidden or subjective.
