HepG2 chr19 Vitessce view

Full spec: https://users.abdenlab.org/voy/vitessce_cvh/hepg2_sci/chr19/chr19.json

Source: ENCODE ENCFF960GTR / ENCSR411RGL; GRCh38 chr19 only.
2,823 regulatory elements, 1,034 gene/TSS columns, 4,225 reported links.
Scores are regulatory-link predictions, not expression measurements.

Layout matches the existing chr4 view: cCRE class heatmap, ClinVar count
strip, element-by-gene heatmap, gene list, and ClinVar overlap groups.
Shared row navigation/highlighting, compact hover labels, and one left
axis title are preserved. Full variant details remain in metadata CSVs.

ClinVar source: /net/public_html/users/voy/clinvar_hg38_all.vcf.gz
No clinical-significance or phenotype filter. 255,991 chr19 records;
14,780 distinct variants overlap 973 regulatory elements.
Intervals use [POS-1, POS-1+len(REF)), including indel anchor bases.

Rebuild: python build_chr19.py
Validate: python validate_build.py
See validation.json and clinvar.validation.json for checks and provenance.
The build requires the source paths recorded there, Python, and bedtools.
Existing chr4 files are preserved. Browser rendering has not been checked.
