Introduction | Installation | Step 1. Prepare VCF genotypes and annotation | Step 2. Compute the primary twelve-variant LD-gradient example | Step 3. Inspect the LDTrack object and pairwise statistics | Step 4. Inspect the LD matrix and quantify the LD gradient | Step 5. Draw the triangular LD heatmap | Step 6. Add gene structure and natural-variant markers | Step 7. Compare the LD-gradient, low-LD, and two-variant regions | Step 8. Control samples, variant types, LD methods, and genotype retention | Select samples | Select variant types | Retain the dosage matrix when needed | Use D-prime cautiously | Step 9. Interpret LD and pass the selected region downstream | Session information
