Building input objects

Constructing the individual-level and summary-statistic S4 containers from manifests or by hand.

LD and quality control

Loading, computing and conditioning LD references, and the allele alignment and LD-mismatch QC that matches summary statistics to them.

Quality Control for GWAS and QTL Summary Statistics

Fine-mapping

SuSiE-family fine-mapping for individual-level QTL data, QTL summary statistics, and GWAS summary statistics.

Post-processing fine-mapping results

TWAS

Training TWAS weights-methods from QTL data (individual-level and summary-statistics, single and multi-context), computing per-gene TWAS Z-scores from GWAS summary statistics, and fine-mapping genes jointly with SNPs so a gene’s PIP is conditioned on the signal beside it.

Cross-context modeling

Multivariate adaptive shrinkage across contexts: learning the covariance structure of effect sharing and shrinking per-context estimates toward it.

Colocalization

Pairwise QTL/GWAS colocalization (coloc.bf_bf) and multi-trait colocalization with ColocBoost.

Heritability and enrichment

SNP heritability from GWAS summary statistics by four estimators, functional enrichment across annotations, postprocessing of external polyfun sLDSC runs, and per-variant molecular-QTL enrichment.
