Key Notes

  • CLI: gatk CollectReadCounts → gatk DenoiseReadCounts → gatk ModelSegments → gatk CallCopyRatioSegments.
  • Call CNVs using GATK best practices" → Collect read counts, build a panel of normals, denoise tumor coverage, model segments with allelic counts, and call copy ratio states. CLI: gatk CollectReadCounts → gatk DenoiseReadCounts → gatk ModelSegments → gatk CallCopyRatioSegments.

Excerpt From SKILL.md

Step 1: Preprocess Intervals

Goal: Prepare genomic intervals for read counting, handling both WES and WGS modes.

Approach: Use PreprocessIntervals to bin or merge target intervals with appropriate padding.


## For WGS

gatk PreprocessIntervals \
    -R reference.fa \
    --bin-length 1000 \
    --padding 0 \
    -O wgs.interval_list

Step 2: Collect Read Counts

Goal: Count reads per interval for each sample.

Approach: Run CollectReadCounts on each BAM against the preprocessed intervals.

Use cases

  • Use when following GATK best practices or integrating CNV calling with other GATK variant pipelines.

Not for

  • Do not rely on this catalog entry alone for installation or maintenance details.
