Generates standardized quality control reports by aggregating metrics from FastQC, alignment, and other tools using MultiQC. Use when summarizing QC metrics across samples, creating shareable quality reports, or building automated QC pipelines.
Reference examples tested with: Cell Ranger 8.0+, FastQC 0.12+, GATK 4.5+, HISAT2 2.2.1+, MultiQC 1.21+, STAR 2.7.11+, Subread 2.0+, bcftools 1.19+, fastp 0.23+, kallisto 0.50+
Before using code patterns, verify installed versions match. If versions differ:
pip show <package> then help(module.function) to check signatures<tool> --version then <tool> --help to confirm flagsIf code throws ImportError, AttributeError, or TypeError, introspect the installed package and adapt the example to match the actual API rather than retrying.
"Aggregate QC results into one report" → Combine outputs from FastQC, samtools, Picard, and other tools into a single interactive HTML report.
multiqc . (scans current directory for recognized tool outputs)# Aggregate all QC outputs in directory
multiqc results/ -o qc_report/
# Specify output name
multiqc results/ -n my_project_qc
# Include specific tools only
multiqc results/ --module fastqc --module star
MultiQC recognizes outputs from 100+ bioinformatics tools:
